HAMBURG, July 8 (Reuters) - U.S. President Donald Trump on Saturday said it may take time to rein in North Korea's nuclear program, but at a meeting with Chinese President Xi Jinping, said he was confident Washington and Beijing could eventually reach a successful conclusion. Trump, who has urged Xi to use China's economic leverage to pressure Pyongyang, said appreciated what Xi has done. Trump has expressed some impatience with China after North Korea tested an intercontinental ballistic missile that some experts believe has the range to reach Alaska, Hawaii and perhaps the U.S. Pacific Northwest. North Korea said it could carry a large nuclear warhead.
