July 8 (UPI) -- The United States may allow Ukraine to manufacture Patriot air-defense missiles, U.S. President Donald Trump said Wednesday after a meeting with Ukrainian President Volodymyr Zelensky in Turkey.

The comments came during meetings -- both in a group with other leaders and then one-on-one with Zelensky -- at the NATO summit in Ankara, Turkey, The Washington Post reported. Trump also praised Zelensky and his country for their fight against Russia, a major shift in tone from his earlier complaints about Ukraine's president, whom he called "ungrateful."

Trump was sitting next to Zelensky at the summit when he said, "A little birdie told me this, about the fact that we'll give them the right to make Patriots. We'll show them how to do it; it's very complex actually. But it's -- you'll figure out the complexity quickly," The Hill reported.
