North Korean leader Kim Jong-un and China's Xi Jinping have agreed to expand co-operation in the areas of politics, economy and culture at a summit in Pyongyang that opened a new chapter in ties, the North's official KCNA news agency says.
Making his first visit in seven years to China's only formal treaty ally, Xi told Kim he aimed to drive progress in ties, and both agreed to strive for closer strategic communication through visits by high-level officials, KCNA said on Tuesday.
Kim told Xi he would fully support the "One China principle", which Beijing viewed as meaning that both sides of the Taiwan Strait belonged to one country, regardless of changes in the international situation, it said.
