As of 2017 Beijing Skyrizon Aviation had purchased a 41% holding in Motor Sich, but in September 2017 a Ukrainian court froze the holding for national security reasons. Beijing Skyrizon Aviation had agreed to invest $250 million in the Ukrainian plants, and to set up an assembly and servicing plant in Chongqing in southwest China.[5] When the authorities of the United States criticized Ukraine for selling engines from Motor Sich to China, Ukrainian politician Oleh Lyashko stated, "If the United States don't want that us began to sell to the Chinese, let them buy our aircraft engines."[6]
