North Korean leader Kim Jong-un is in China for a 3-day trip, his fourth visit to the country over the past year. Few details of his trip have been released, but he is expected to hold talks with Chinese President Xi Jinping over trade and the possible upcoming nuclear summit with the United States. Kim’s visit comes as U.S. and Chinese officials are holding trade talks in hopes of ending the ongoing trade war between the two countries. In December, President Trump and Chinese President Xi Jinping agreed to a temporary truce, which is due to expire in March.
