Russia’s Defense Ministry has no problems over the need to replace Ukrainian components 

Nearly 700 parts and components for weapons and other military hardware that until recently have been manufactured in cooperation with Ukraine will have to be substituted for this year, Russian Defense Minister Sergey Shoigu said on Tuesday.

“By the end of the year nearly 700 titles of components for armaments and military hardware, originally produced in cooperation with Ukrainian enterprises, will have to be substituted for by the end of 2015,” he said.
