BEIJING (Reuters) - U.S. President Donald Trump will ask China to cut its financial links with North Korea and to abide by U.N. sanctions when meeting with Chinese President Xi Jinping in Beijing, a senior White House official said on Wednesday. Trump arrived in Beijing on Wednesday afternoon from South Korea for a two-night stop in the Chinese capital as part of his marathon Asia tour. The U.S. president was undecided on whether to declare North Korea a state sponsor of terrorism by the end of his trip, the official said, speaking to reporters on-board Air Force One. Trump believes any talks with the North would require reducing threats, ending provocations and movement toward denuclearization and that no deal can be achieved without denuclearisation, the official added.
