Mikser said that Estonia is a firm supporter of Ukraine's European aspirations, spokespeople for the Foreign Ministry in Tallinn said.

"Despite the difficult situation in the region, Ukraine has made remarkable progress in reforming the state in the economy, the financial and energy sectors alike," the Estonian minister said, stressing the importance of the continuation of reforms.

"After the enactment in the second half of last year of the association agreement between the EU and Ukraine, including a free trade agreement, economic relations between the two sides are intensifying. Yet in this we also expect improvement of the business environment from Ukraine," Mikser said.

The situation in the eastern part of Ukraine was also talked about at the meeting.

"The fourth anniversary of the annexation of Crimea is nearing, yet unfortunately the situation in eastern Ukraine continues to be tense and no progress has been made in solving the conflict," Mikser said, adding that Estonia and Europe will not cease supporting Ukraine.

The deputy prime minister of Ukraine thanked the Estonian foreign minister for support.

Mikser observed that EU foreign ministers will discuss the subject of Ukraine at the meeting of the Foreign Affairs Council on March 19. "That discussion will be preceded by a visit to Ukraine by the EU high representative on foreign and security policy, Federica Mogherini, and getting a firsthand look at the situation there is definitely necessary," the Estonian minister said.

Mikser and Klympush-Tsintsadze took part in a conference on the EU Eastern Partnership in Tallinn on Friday. Mikser said that developing the Eastern Partnership is a long-term priority for Estonia which the country has been supporting both on the political level and through development cooperation.

In addition, Mikser raised the issue of large Estonian investments which remains unsolved to this day, observing that this may have an impact on the interest of Ukrainian investors to take part in further privatization in Ukraine, among other things, spokespeople for the Foreign Ministry said.
