Chinese President Xi Jinping's top envoy returned to Beijing on Monday after a four-day visit to Pyongyang but seems to have been snubbed by leader Kim Jong-un.
It would be a serious snub to Song Tao, who is also head of the Chinese Communist Party's International Liaison Department.
China's official Xinhua news agency said Song "met and held talks with leaders of the Central Committee of the Workers Party" but made no mention of Kim.
"The two sides also exchanged views on relations between the two parties and the two countries, and on the Korean Peninsula issue and other issues of common concern."
All that is certain is that he met Choe Ryong-hae, a vice party chairman thought to be Kim's right-hand man, and Foreign Minister Ri Su-yong.
North Korea's state media did not mention any meeting between Song and Kim either. Instead, the North's official Korean Central News Agency and the Rodong Sinmun daily were packed with propaganda critical of the U.S., South Korea and Japan.
In an editorial entitled "War Servants Will Face Bitter Disgrace," KCNA lambasted U.S. President Donald Trump as a "stingy trader and warmonger."
