U.S. military action against North Korea is not an imminent possibility, U.S. Special Representative for North Korea Policy Joseph Yun said on Thursday, while stressing that “all options are on the table” to deter Pyongyang.

Speaking to press in Tokyo, Japan, Yun stressed that the United States backed a diplomatic solution to the issue of North Korea’s nuclear and ballistic missile program.

“Our policy is very much for the peaceful resolution of the North Korean nuclear crisis. We’ve said over and over again that what we want to see is dialogue,” the Special Representative said, in comments carried by Reuters.
