Deputy Foreign Minister of Turkey Ahmet Yıldız has said the international community must not get tired of Ukraine. He called on world leaders to solve the "Ukrainian issue."

"Ukraine is becoming stronger, despite what is happening in Crimea and in Donbas… We, of course, support the letter of international law and support the inhabitants of Crimea, especially the Crimean Tatars. We believe that the international community should not get tired of Ukraine and understand that this problem is real," Yildiz said on Thursday in London.

He added that despite the fact Turkey is not seeing significant progress in the implementation of the Minsk accords, it supports them because the agreement is "the basic framework, the plan that must be carried out."

Yildiz said Turkey is also supporting Ukraine's reform process. He added it is necessary to make some legislative changes, saying there are some things Ukraine's government could do today.

"There are some administrative steps which could be taken to attract foreign investors," he said.
