German Chancellor Angela Merkel arrived on Sunday in Turkey to negotiate a plan to stop the influx of migrants into the EU.

The German leader should meet with President Recep Tayyip Erdogan and Prime Minister Ahmet Davutoglu in Istanbul.

The main topic of the talks will be the "Action Plan" announced on Thursday by the European Union to help Ankara stop the influx of migrants, especially those who fled the Syria war by staying in their territory.

But Turkey, which already hosts more than two million refugees, calls this plan a common "draft of an unacceptable budget," estimating that it is necessary at least three billion euros for the first year.

The EU wants Ankara to receive more refugees and strengthen border controls in exchange for funds, renewing the debate on Turkey's EU candidacy and facilitating access to visas.

"If Germany and Turkey fail to reach an agreement, there is no other solution in sight and the massive migration of Syria and others in the EU will continue," reveals the European Stability Initiative analytical center on Merkel's visit. (Hina)
