North Korean Foreign Minister Ri Yong-ho told reporters on the sidelines of the U.N. General Assembly that Pyongyang might consider testing a hydrogen bomb over the Pacific Ocean after the United States widened economic sanctions against the hermit kingdom.

North Korea says it is “on the brink of war” with the U.S. In an interview with CBS News’ Ben Tracy, one of the nation’s senior officials has accused the Trump administration of wanting to “annihilate” his country and blamed the escalating tension on the Korean Peninsula squarely on the U.S. and South Korea. 

State media reported that Xi congratulated Trump on his election and said cooperation was the “only correct choice” for China and the U.S., the world’s two biggest economies.
