U.S. Secretary of State Mike Pompeo said on Monday that he regrets the U.S. hadn’t made more progress in resolving issues with China and North Korea. 

In an interview with Bloomberg Television, Pompeo said that North Korean leader Kim Jong-un “has not yet made the decision that he is actually prepared to execute” on a commitment to give up his nuclear weapons after two summits with U.S. President Donald Trump.

Pompeo stressed that North Korea, however, has conducted no nuclear or long-range ballistic missile tests since it started talks with Washington. 

As for China, the U.S. top diplomat said he regrets that hard issues between China and the U.S. have not been resolved, adding the two nations still have an unfair trading relationship and China's theft of intellectual property remains a problem. 

However, Pompeo assessed that the Trump administration has made the world a safer place than it was four years ago.
