BEIJING (AP) — The motorcade of North Korean leader Kim Jong Un has headed out on the second full day of his visit to China.

Kim could not be seen but the limousine he uses was observed zipping east down a main thoroughfare in Beijing on Wednesday.

His trip to Beijing has been shrouded in secrecy. North Korean and Chinese state media have announced his visit but provided no details of what he has done since arriving by train on Tuesday morning.

China is North Korea's only major ally, and Kim is likely consulting and coordinating with Chinese leader Xi Jinping and others ahead of a possible second summit with President Donald Trump.
