BEIJING (Reuters) - North Korea leader Kim Jong Un has visited China, Bloomberg reported on Monday citing three unnamed sources, in what would be his first known overseas trip since taking power in 2011 and ahead of a potential summit with U.S. President Donald Trump. Beijing has traditionally been the closest ally of secretive and isolated North Korea. Visits to China by Kim Jong Il were only confirmed by both China and North Korea once he had left the country. Kim Jong Il travelled by private train during his rare visits to China or Russia under tight security. Diplomats and other sources have said Kim Jong Il avoided flying for overseas trips due to security concerns.
