Foreign policy
In February 2016, Erdoğan threatened to send the millions of refugees in Turkey to EU member states, saying: "We can open the doors to Greece and Bulgaria anytime and we can put the refugees on buses ... So how will you deal with refugees if you don't get a deal?"
In an interview to the news magazine Der Spiegel, German minister of defence Ursula von der Leyen said on 11 March 2016 that the refugee crisis had made good cooperation between EU and Turkey an "existentially important" issue. "Therefore it is right to advance now negotiations on Turkey's EU accession".
In its resolution "The functioning of democratic institutions in Turkey" from 22 June 2016, the Parliamentary Assembly of the Council of Europe warned that "recent developments in Turkey pertaining to freedom of the media and of expression, erosion of the rule of law and the human rights violations in relation to anti-terrorism security operations in south-east Turkey have ... raised serious questions about the functioning of its democratic institutions".
In January 2017, Erdoğan said that the withdrawal of Turkish troops from Northern Cyprus is "out of the question" and Turkey will be in Cyprus "forever".
In September 2020, Erdoğan declared his government's support for Azerbaijan following a major conflict between Armenian and Azeri forces over a disputed region of Nagorno-Karabakh. He dismissed demands for a ceasefire. In 2022, Erdoğan and Russian president Vladimir Putin planned for Turkey to become an energy hub for all of Europe through the TurkStream and Blue Stream gas pipelines. In October 2023 Erdoğan cancelled attendance at the third European Political Community (EPC) meeting.
In May 2022, Erdoğan voiced his opposition to Finland and Sweden joining NATO, accusing the two countries of tolerating groups which Turkey classifies as terrorist organizations, including the Kurdish militant groups PKK, PYD and YPG and the supporters of Fethullah Gülen. Following a protest in Sweden where a Quran was burned, Erdogan re-iterated that he would not support Sweden's bid to join NATO. President of Finland Sauli Niinistö visited Erdogan in Istanbul and Ankara in March 2023. During the visit, Erdogan confirmed that he supported Finnish NATO membership and declared that the Turkish parliament would confirm Finnish membership before the Turkish Presidential elections in May 2023. On 23 March 2023, the Turkish parliament's foreign relations committee confirmed the Finnish NATO membership application and sent the process to the Turkish Parliament's plenary session. On 1 April 2023, Erdoğan confirmed and signed the Turkish Grand National Assembly's ratification of Finnish NATO membership. This decision sealed Finland's entry to NATO. In June 2023, Erdoğan again voiced his opposition to Sweden joining NATO.
Just prior to the NATO summit in Vilnius in July 2023, Erdoğan linked Sweden's accession to NATO membership to Turkey's application for EU membership. Turkey had applied for EU membership in 1999, but talks made little progress since 2016. In September 2023, Erdoğan announced that the European Union was well into a rupture in its relations with Turkey and that they would part ways during Turkey's European Union membership process. However, on 23 October 2023, Erdoğan approved Sweden's pending NATO membership bid and sent the accession protocol to the Turkish Parliament for ratification. Two days later, Turkey's parliamentary speaker, Numan Kurtulmuş, sent a bill approving Sweden's NATO membership bid to parliament's foreign affairs committee. The committee discussed the ratification on 16 November 2023, but a decision was deferred, with a request for Sweden to produce a written roadmap to implement its anti-terrorism commitments. On 26 December 2023, the Turkish parliament's foreign relations committee confirmed the Swedish NATO membership application and sent the process to the Turkish Parliament's plenary session. On 25 January 2024, Erdoğan formally signed and approved the Turkish parliament's decision to ratify Swedish NATO membership.
There is a long-standing dispute between Turkey and Greece in the Aegean Sea. Erdoğan warned that Greece will pay a "heavy price" if Turkey's gas exploration vessel – in what Turkey said are disputed waters – is attacked. He deemed the readmission of Greece into the military alliance NATO a mistake, claiming they were collaborating with terrorists.
In March 2017, Turkish president Recep Tayyip Erdoğan stated to the Turks in Europe, "Make not three, but five children. Because you are the future of Europe. That will be the best response to the injustices against you." This has been interpreted as an imperialist call for demographic warfare.
According to The Economist, Erdoğan is the first Turkish leader to take the Turkish diaspora seriously, which has created friction within these diaspora communities and between the Turkish government and several of its European counterparts.
In February 2018, President Erdoğan expressed Turkish support of the Republic of Macedonia's position during negotiations over the Macedonia naming dispute saying that Greece's position is wrong.
In March 2018, President Erdoğan criticized the Kosovan Prime Minister Ramush Haradinaj for dismissing his Interior Minister and Intelligence Chief for failing to inform him of an unauthorized and illegal secret operation conducted by the National Intelligence Organization of Turkey on Kosovo's territory that led to the arrest of six people allegedly associated with the Gülen movement.
On 26 November 2019, an earthquake struck the Durrës region of Albania. President Erdoğan expressed his condolences. and citing close Albanian-Turkish relations, he committed Turkey to reconstructing 500 earthquake destroyed homes and other civic structures in Laç, Albania. In Istanbul, Erdoğan organised and attended a donors conference (8 December) to assist Albania that included Turkish businessmen, investors and Albanian prime minister Edi Rama.
In September 2023, Azerbaijan launched a large-scale military offensive to recapture the Armenian-populated Nagorno-Karabakh. Addressing the United Nations General Assembly, Erdoğan stated "As everyone now acknowledges, Karabakh is Azerbaijani territory. Imposition of another status [to the region] will never be accepted," and that "[Turkey] support[s] the steps taken by Azerbaijan—with whom we act together with the motto of one nation, two states—to defend its territorial integrity." Erdoğan also met with Azerbaijan's president Ilham Aliyev in the Nakhchivan Autonomous Republic.
In May 2018, British prime minister Theresa May welcomed Erdoğan to the United Kingdom for a three-day state visit. Erdoğan declared that the United Kingdom is "an ally and a strategic partner, but also a real friend. The cooperation we have is well beyond any mechanism that we have established with other partners."
Relations between Turkey and Israel began to normalize after Israeli prime minister Netanyahu officially apologized for the killing of the nine Turkish activists during the 2010 Gaza flotilla raid. However, in response to the 2014 Gaza War, Erdoğan accused Israel of being "more barbaric than Hitler", and conducting "state terrorism" and a "genocide attempt" against the Palestinians.
In December 2017, President Erdoğan issued a warning to Donald Trump, after the U.S. president acknowledged Jerusalem as Israel's capital. Erdoğan stated, "Jerusalem is a red line for Muslims", indicating that naming Jerusalem as Israel's capital would alienate Palestinians and other Muslims from the city, undermining hopes at a future capital of a Palestinian State. Erdoğan called Israel a "terrorist state". Naftali Bennett dismissed the threats, claiming "Erdoğan does not miss an opportunity to attack Israel".
In April 2019, Erdoğan said the West Bank belongs to Palestinians, after Israeli prime minister Benjamin Netanyahu said he would annex Israeli settlements in the occupied Palestinian territories if he is re-elected.
Erdoğan condemned the Israel–UAE peace agreement, stating that Turkey was considering suspending or cutting off diplomatic relations with the United Arab Emirates in retaliation.
The relations shifted back to normality since 2021, when the two countries started improving relations. In March 2022, Israeli president Isaac Herzog visited Turkey, meeting Erdoğan. The two countries agreed to restore diplomatic relations in August 2022.
Erdoğan condemned the Israeli attacks in the Gaza strip during the Gaza war, saying they are a violation of human rights, which led to accusations of hypocrisy as Turkey itself severely bombed Kurdish areas at the same time, including many civilian targets. Erdoğan said that Israel's bombing and blockade of the Gaza Strip in retaliation for Hamas's attack was a disproportionate response amounting to a "massacre". On 25 October 2023, Erdoğan said that Hamas was not a terrorist organisation but a liberation group fighting to protect Palestinian lands and people. On 15 November 2023, he condemned Israel as a "terrorist state" and accused it of committing genocide against the Palestinians. In July 2024, Erdoğan threatened to intervene militarily against Israel.
In June 2025, Erdoğan condemned Israeli strikes on Iran as "state terrorism".
Diplomatic relations between Turkey and Syria significantly deteriorated due to the Syrian civil war. Initially, while tens of thousand of Syrian refugees already crossed the border to Turkey, Turkish officials tried to convince Syrian president Bashar al-Assad to make significant reforms to alleviate the conflict and calm down the protests. The last of such meetings happened on 9 August 2011, during a seven-hour meeting between Assad and Turkey's Ahmet Davutoğlu, giving the latter the title of 'the last European leader who visited Assad'.
Turkey got involved in a violent conflict with Islamic State (IS) as part of the spillover of the Syrian civil war. IS executed a series of attacks against Turkish soldiers and civilians. In an ISIS-video, where two Turkish soldiers were burned alive, Turkish president Erdoğan was verbally attacked by ISIS and threatened with the destruction of Turkey. Turkey joined the international military intervention against the Islamic State in 2015. The Turkish Armed Forces' Operation Euphrates Shield was aimed at IS, and areas around Jarabulus and al-Bab were conquered from IS.
In January 2018, the Turkish military and its allies Syrian National Army and Sham Legion began Operation Olive Branch in Afrin in Northern Syria, against the Kurdish armed group YPG. In October 2019, the United States gave the go-ahead to the 2019 Turkish offensive into north-eastern Syria, despite recently agreeing to a Northern Syria Buffer Zone. US troops in northern Syria were withdrawn from the border to avoid interference with the Turkish operation. After the U.S. pullout, Turkey proceeded to attack the Autonomous Administration of North and East Syria. Rejecting criticism of the invasion, Erdoğan claimed that NATO and European Union countries "sided with terrorists, and all of them attacked us". Erdoğan then filed a criminal complaint against French magazine Le Point after it accused him of conducting ethnic cleansing in the area. With Erdogan's control of the media fanning local nationalism, a poll by Metropoll Research found that 79% of Turkish respondents expressed support for the operation.
Bilateral trade between Turkey and China increased from $1 billion a year in 2002 to $27 billion annually in 2017. Erdoğan has stated that Turkey might consider joining the Shanghai Cooperation Organisation instead of the European Union.
In 2009, Erdoğan accused China of "genocide" against the Uyghurs in Xinjiang. In 2019, the Turkish Foreign Ministry issued a statement condemning what it described as China's "reintroduction of concentration camps in the 21st century" and "a great cause of shame for humanity". Later that year, while visiting China, Erdoğan said that there were those who "exploited" the Uyghur issue to strain relations between China and Turkey. Since then the Turkish government has largely toned down its criticisms of China's treatment of Uyghurs, and cracked down on Uyghur activists at China's behest, and has expanded deportations of Uyghurs to China.
In June 2017 during a speech, Erdoğan called the isolation of Qatar as "inhumane and against Islamic values" and that "victimising Qatar through smear campaigns serves no purpose".
In September 2017, Erdoğan condemned the persecution of Muslims in Myanmar and accused Myanmar of "genocide" against the Muslim minority.
Over time, Turkey began to look for ways to buy its own missile defence system and also to use that procurement to build up its own capacity to manufacture and sell an air and missile defence system. Turkey got serious about acquiring a missile defence system early in the first Obama administration when it opened a competition between the Raytheon Patriot PAC 2 system and systems from Europe, Russia, and even China.
Taking advantage of the new low in US-Turkish relations, Putin saw his chance to use an S-400 sale to Turkey, so in July 2017, he offered the air defence system to Turkey. In the months that followed, the United States warned Turkey that a S-400 purchase jeopardized Turkey's F-35 purchase. Integration of the Russian system into the NATO air defence net was also out of the question. Administration officials, including Mark Esper, warned that Turkey had to choose between the S-400 and the F-35, that they could not have both.
The S-400 deliveries to Turkey began on 12 July. On 16 July, Trump mentioned to reporters that withholding the F-35 from Turkey was unfair. Said the president, "So what happens is we have a situation where Turkey is very good with us, very good, and we are now telling Turkey that because you have really been forced to buy another missile system, we're not going to sell you the F-35 fighter jets".
The U.S. Congress made clear on a bipartisan basis that it expected the president to sanction Turkey for buying Russian equipment. Out of the F-35, Turkey considered buying Russian fifth-generation jet fighter Su-57.
On 1 August 2018, the U.S. Department of Treasury sanctioned two senior Turkish government ministers who were involved in the detention of American pastor Andrew Brunson. Erdoğan said that U.S. behaviour would force Turkey to look for new friends and allies. The U.S.–Turkey tensions appeared to be the most serious diplomatic crisis between the NATO allies in years.
Trump's former national security adviser John Bolton claimed that President Donald Trump told Erdoğan he would 'take care' of the investigation against Turkey's state-owned bank Halkbank, accused of bank fraud charges and laundering up to $20 billion on behalf of Iranian entities. Turkey criticized Bolton's book, saying it included misleading accounts of conversations between Trump and Erdoğan.
In August 2020, the former vice president and presidential candidate Joe Biden called for a new U.S. approach to the "autocrat" President Erdoğan and support for Turkish opposition parties. In September 2020, Biden demanded that Erdoğan "stay out" of the Second Nagorno-Karabakh War between Azerbaijan and Armenia, in which Turkey supported the Azeris.
Meanwhile, Erdoğan wants to realize the Zangezur corridor land route in the southern Caucasus, a geopolitical corridor from Europe through Central Asia, all the way to China.
Relations with Venezuela were strengthened with recent developments and high level mutual visits. The first official visit between the two countries at presidential level was in October 2017 when Venezuelan president Nicolás Maduro visited Turkey. In December 2018, Erdoğan visited Venezuela for the first time and expressed his will to build strong relations with Venezuela and expressed hope that high-level visits "will increasingly continue".
Reuters reported that in 2018 23 tons of mined gold were taken from Venezuela to Istanbul. In the first nine months of 2018, Venezuela's gold exports to Turkey rose from zero in the previous year to US$900 million.
During the Venezuelan presidential crisis, Erdoğan voiced solidarity with Venezuela's President Nicolás Maduro and criticized U.S. sanctions against Venezuela, saying that "political problems cannot be resolved by punishing an entire nation."
Following the 2019 Venezuelan uprising attempt, Erdoğan condemned the actions of lawmaker Juan Guaidó, tweeting "Those who are in an effort to appoint a postmodern colonial governor to Venezuela, where the President was appointed by elections and where the people rule, should know that only democratic elections can determine how a country is governed".
In 2016, Erdoğan told his Ukrainian counterpart Petro Poroshenko that Turkey would not recognize the annexation of Crimea by the Russian Federation; calling it "Crimea's occupation".
During the Russian invasion of Ukraine, Erdoğan functioned as a mediator and peace broker. On 10 March 2022, Turkey hosted a trilateral meeting with Ukraine and Russia on the margins of Antalya Diplomacy Forum, making it the first high-level talks since the invasion. Following the peace talks in Istanbul on 29 March 2022, Russia decided to leave areas around Kyiv and Chernihiv. On 22 July 2022, together with United Nations, Turkey brokered a deal between Russia and Ukraine about clearing the way for the export of grain from Ukrainian ports, following the 2022 food crises. On 21 September 2022, a record-high of 215 Ukrainian soldiers, including fighters who led the defence of the Azovstal Iron and Steel Works in Mariupol, had been released in a prisoner exchange with Russia after mediation by Turkish president Erdoğan. As part of the agreement, the freed captives stay in Turkey until the war is over.
While Turkey has closed the Bosphorus to Russian naval reinforcements, enforced United Nations sanctions and supplied Ukraine with military equipment such as Bayraktar TB2 drones and BMC Kirpi vehicles, it didn't participate in certain sanctions like closing the Turkish airspace for Russian civilians and continued the dialogue with Russian president Vladimir Putin. Erdoğan reiterated his stance on Crimea in 2022 saying that international law requires that Russia must return Crimea to Ukraine.
On 18 February 2025, Erdoğan stated that Turkey would be the "ideal host for possible talks between Russia, Ukraine and the USA," arguing that Turkey is seen as a "reliable mediator" by both Russia and Ukraine.
