US President Donald Trump leaves on Friday for Asia and high-stakes talks with Chinese leader Xi Jinping -- as Washington played down speculation that he could meet North Korea's Kim Jong Un.

Trump is set to meet Xi in South Korea on the last day of his trip, aiming for a "deal on everything" to end a bitter trade war between the world's two biggest economies.

The 79-year-old will also visit Malaysia and Japan on his first Asian trip since he returned to the White House in January in a blaze of tariffs and geopolitical deal-making.

A senior US official said on Friday that Trump would "deliver for the American people in one of the most economically vibrant regions of the world, signing a series of economic agreements."
