TOKYO (Reuters) - U.S. President Donald Trump and Japanese Prime Minister Shinzo Abe agreed in a telephone conversation on Wednesday that pressure should be maintained on North Korea, a senior Japanese government official told reporters. The two men also agreed that  dialogue for the purpose of dialogue  was meaningless,  the official said. In recent weeks North Korea has launched two missiles over Japan and conducted its sixth nuclear test, and may be fast advancing toward its goal of developing a nuclear-tipped missile capable of hitting the U.S. mainland. U.S. Secretary of State Rex Tillerson said last weekend that Washington was directly communicating with Pyongyang on its nuclear and missile programs but that Pyongyang had shown no interest in dialogue. Trump later dismissed any prospect of talks with North Korea as a waste of time.     During the 12-minute telephone conversation, Abe also offered condolences over the mass shooting in Las Vegas, and told Trump that Japan was  100 percent  behind the American people. Trump will be traveling to Japan, China, South Korea, Vietnam and the Philippines next month.
