Ukraine may be looking to Japan for help building Patriot air-defense missiles, after U.S. President Donald Trump indicated that Washington would give Kyiv a license to manufacture the advanced weapons.

Ukrainian President Volodymyr Zelenskyy said this week that his country is interested in working with 91AV原创 Mitsubishi Heavy Industries, which is one of the few companies to hold a license to manufacture the Patriot missiles.

Ukraine is in dire need of the weapons to defend against Russia’s ongoing missile onslaught.
