"This is my idea that could be implemented — to produce weapons in cooperation with the Americans on the Ukrainian territory," Chaly said in an interview with the 112 Ukraine broadcaster.
He also expressed hope that the United States would soon give a positive "signal" on granting Ukraine lethal weapons.
In early August, Chaly reportedly claimed that the issue of supplies of lethal weapons to Ukraine could be considered after the US presidential elections.
The US military assistance to Kiev is currently limited to supplying uniforms and equipment, including counter-battery radars, unmanned aerial vehicles (UAV) and means of secure communication, but it provides no lethal weapons.
Moscow has repeatedly warned against plans to supply arms to Ukraine, as it fears it would only lead to a further escalation of the conflict in Donbas, where Ukraine launched a military operation in April 2014, after local residents refused to recognize the new government in Kiev that they viewed as illegitimate.
