Washington: U.S. President Donald Trump remains open to engaging in dialogue with North Korean leader Kim Jong-un "without any preconditions," a White House official said Tuesday, amid speculation that Trump could seek to meet Kim when he visits South Korea to attend the Asia-Pacific Economic Cooperation (APEC) summit. According to Yonhap News Agency, the official made the remarks in response to a question from the agency, after North Korean leader Kim expressed openness to resuming talks with the United States if Washington drops its demand for the North's denuclearization. "President Trump in his first term held three historic summits with North Korean Leader Kim Jong-un that stabilized the Korean Peninsula," the official said. "U.S. policy on North Korea has not changed. President Trump remains open to talking with Kim Jong-un without any preconditions," the official added.
