Beijing - Kazakhstan President Nursultan Nazarbayev met with China's top legislator Wu Banguo Thursday, pledging to step up bilateral cooperation, state media reported.

Wu, chairman of the Standing Committee of China's National People's Congress, said relations between the two countries were at an all-time high and that China would work with Kazakhstan to enhance cooperation in fields such as energy, transportation, mineral resources development and infrastructure construction, the Xinhua news agency reported.

Nazarbayev, who kicked off a five-day visit to China Wednesday, also met with Chinese Vice Premier Wang Qishan.

"With the global financial crisis still spreading, the two countries should work jointly to tackle challenges," Wang said.

Nazarbayev responded by saying that Kazakhstan is supportive of entrepreneurs carrying out projects beneficial to both countries and business cooperation would also prove a push for improved state-to-state relations.

Nazarbayev also reaffirmed a commitment to fight terrorism in the region, China Radio International reported.

Kazakhstan and China share a border of more than 1,700 kilometres and have previously cooperated on a Kazakhstan-China oil pipeline, which is already in operation, and a natural gas pipeline still under construction.

Nazarbayev is to attend a regional economic summit, the Bo'ao Forum for Asia, in Hainan from Sunday through Tuesday.(dpa)
