Azerbaijani President Ilham Aliyev hailed strong relations with Türkiye, saying that the unity of the two countries is crucial not only for the region but for Eurasia.

Speaking at a joint news conference with President Recep Tayyip Erdoğan, Aliyev also said the unification of the Turkic world and the coexistence of peoples with common cultures would strengthen each member of the Organization of Turkic States (OTS).

For his part, Erdoğan said Türkiye will continue to work to get Azerbaijan's credentials at the Parliamentary Assembly of the Council of Europe (PACE) validated.

"We will continue our support and efforts for Azerbaijan until the decision (not ratifying their credentials) is overturned," the president said.

Last month, PACE voted to deny validation to the credentials of the Azerbaijani delegation to the body, alleging that it has not fulfilled major commitments under its Council of Europe membership.

Erdogan also said that with the end of Armenia's nearly 30-year occupation of Karabakh, a historic window of opportunity opened for lasting peace in the region, adding that it is "crucial" that this window does not close.

On trade ties, Erdogan said: "The total Turkish-Azerbaijani trade volume last year reached $7.5 billion (TL 231.62 billion) for the first time. We will step up our efforts to achieve a $15 billion target," Erdogan added.

Erdogan on Monday welcomed Aliyev in the capital Ankara to discuss all aspects of bilateral relations, as well as steps to further cooperation between the two countries.

Aliyev's visit to Ankara is his first trip abroad since being reelected earlier this month.
