Migrants, gas interconnections and road infrastructure projects have topped the agenda at a meeting between Bulgarian President Rosen Plevneliev and Turkish PM Ahmet Davutoglu, the head of state's press office has said.

The two leaders met at the 70th session of the United Nations General Assembly that is being held in New York.

Gas interconnectors are envisaged to help Bulgaria diversify supplies by enabling gas deliveries from the Southern Gas Corridor.

Politicians on both sides of the borders have been delaying for years a move to kick off work on Bulgaria-Turkey and Bulgaria-Greece links. Construction of the interconnections was expected to be launched in 2016 and 2015 respectively, but could be postponed further as Greece and Turkey have early elections this year.

On migrants, Plevneliev points to Bulgaria's successful bilateral cooperation with Turkey - but also to the trilateral that involves Greece - on border control mechanisms. He cites the example of an earlier agreement to establish a police and customs cooperation center jointly run by the three countries.  

The conversation with Davutoglu takes place before Plevneliev's meeting with UN Secretary General Ban Ki-moon.
