Today, a Chinese news service is referring to recent talks between the new Chinese leadership and Kim Jong Un's special envoy to Beijing. Relations between both allies seem to become tougher:
North Korea's special envoy meets with a different "expression":
China demanding, the North must abandon the nuclear [issue].
China doesn't put forward the "relationship of sworn brothers".
China, U.S., South Korea - devoted to ask
North Korea to "abandon the nuclear issue".
