Canada will send 200 military trainers to Ukraine, joining the U.S. and Britain in an effort to shore up the eastern European country's battered forces.

Prime Minister Stephen Harper and Defense Minister Jason Kenney announced the move Tuesday.

The troops will join U.S. and British soldiers early this summer, and the mission will last until March 31, 2017.

Harper says Canada's military contribution addresses a number of requests from the government of Ukraine. He said it is intended to help the country in its efforts to maintain sovereignty, security and stability in the face of Russian aggression.

Most of the trainers are expected to be housed at a NATO training center in Yavoriv, near the Polish border.
