China's vice foreign minister Zhang Zhijun arrived in Pyongyang and discussed diplomatic ties with North Korean officials, the North's state media said Sunday.
Zhang held talks Sunday with the North's first vice foreign minister Kim Kye-Gwan and several other senior officials, the Korean Central News Agency said.
"At the talks both sides exchanged views on boosting the bilateral friendship and matters of mutual concern," KCNA said in a statement.
China is the sole major ally and economic lifeline of the impoverished communist nation.
It is also the chair of long-stalled six-party nuclear disarmament talks with the North, which also involve South Korea, the US, Japan and Russia.
Kim is Pyongyang's chief envoy for the six-party forum, which has been on a standstill since the last meeting in December 2008 and Beijing wants to revive in a process to ease tension on the peninsula.
