President Recep Tayyip Erdoğan will visit Azerbaijan for the third time on Tuesday since the Nagorno-Karabakh region was liberated from Armenian occupation.

Erdoğan will meet his counterpart Ilham Aliyev and attend the inauguration of Fuzuli International Airport.

The Turkish leader's last trip to Azerbaijan was in June, when he visited the historic Karabakh town of Shusha, the country's cultural capital that had been occupied by Armenia for 28 years.

Erdoğan and Aliyev signed the Shusha Declaration during that trip, a pact focused on defense cooperation and establishing new transportation routes.

The agreement also affirms that Turkey and Azerbaijan will work together in the face of any external threat.

The Turkish president was also a guest of honor at a special parade held in December 2020 to celebrate Azerbaijan's Nagorno-Karabakh victory.

In his address at the event, Erdoğan reaffirmed Ankara's unwavering support for Baku's security and development goals, vowing that the two countries will make the region a "prosperous, developed and more livable place for our children."

Relations between the former Soviet republics of Azerbaijan and Armenia have been tense since 1991 when the Armenian military occupied Nagorno-Karabakh, a territory internationally recognized as part of Azerbaijan, and seven adjacent regions.

New clashes erupted on Sept. 27, 2020, with the Armenian army launching repeated attacks on civilians and Azerbaijani forces, violating several humanitarian cease-fire agreements.

During the 44-day conflict, Azerbaijan liberated several cities and some 300 settlements and villages that were occupied by Armenia for nearly three decades.

The fighting ended on Nov. 10, 2020, after the two countries signed an agreement brokered by Russia.
