Former U.S. President Jimmy Carter has offered to travel to Pyongyang on behalf of the Trump administration to try to defuse the current tensions.

Carter, 93, told The New York Times that the current U.S. administration "greatly overestimates China's influence on the regime," adding that there seems to be no relationship between North Korean leader Kim Jong-un and Chinese President Xi Jinping. He pointed out that Kim has yet to visit China.

He said he had offered his services to National Security Adviser H.R. McMaster. Carter, who has traveled to North Korea on several occasions, expressed concerns about the current situation on the Korean Peninsula, warning of Kim's unpredictable behavior.
