Donald Trump in a New Year letter on Sunday that Moscow was ready for dialogue on a “wide-ranging agenda”, the Kremlin said following a series of failed attempts to hold a new summit.

Trump and Putin also failed to hold a full-fledged meeting in Paris on the sidelines of the centenary commemoration of the Armistice. The two leaders held their one and only summit in Helsinki in July.
