KIEV, June 28 (Xinhua) -- Ukrainian President Petro Poroshenko on Thursday stressed the importance of adding Ukraine's intention to join the North Atlantic Treaty Organization (NATO) and the European Union (EU) into the Constitution, the presidential press service said.

"The European and Euro-Atlantic integration clearly corresponds to the national interests of Ukraine," Poroshenko was quoted as saying during the solemn events to celebrate the Constitution Day of Ukraine.

He said that in the near future he will submit to the parliament draft amendments to the Constitution, which define the membership in the EU and the NATO as Ukraine's strategic goals.

In 2014, when pro-West authorities came to power in Ukraine, Kiev abandoned its multi-vector policy and set a course toward European integration. Furthermore, the parliament revoked Ukraine's non-aligned status, paving the way for membership in military blocs.

Over the past four years, Ukraine has strengthened cooperation with the EU and increased interactions with NATO, but neither organization has promised Kiev near-term membership prospects.

Legislation can be enshrined in the Ukrainian Constitution with the support of at least 300 lawmakers in the 450-seat parliament.
