A day after North Korea signaled it is willing to discuss giving up its nuclear weapons, the South China Morning Post reports that South Korea officials will deliver a “very unconventional” message from Kim Jong Un to the Trump administration. 

SCMP reports:

North Korean leader Kim Jong-un may propose sending his sister, Kim Yo-jong, to the US as part of efforts to launch direct talks between Washington and Pyongyang, according to a South Korean diplomatic source.

That may be one of a number of possible messages South Korean envoy Chung Eui-yong will deliver to US National Security Adviser H.R. McMaster in Washington this week, the source told the South China Morning Post, speaking on the condition of anonymity.

“Kim Jong-un has a certain message, which is not publicised to be delivered directly to the Trump administration. It’s something very unconventional and something very unusual. I don’t know if the US will disclose this message to the public.”

Chung will deliver “conditions from the North Korean side to start some bilateral dialogue with the United States,” the source said.

On Thursday, China’s foreign minister Wang Yi called on the U.S. and North Korea to hold diplomatic talks as soon as possible.

“History tells us that whenever tensions over the Korean peninsula subside, the situation will be clouded by various interferences,” Wang said in Beijing.

“We have now again come to a crucial moment for testing whether the parties involved are truly sincere in resolving the Korean Peninsula nuclear issue.”

“The United States and North Korea must engage in dialogue as soon as possible,” Wang added.
