China and Kazakhstan on Tuesday vowed to boost their strategic partnership and bilateral cooperation.

The pledge came out of a series of meetings between Chinese state leaders and Kazakh President Nursultan Nazarbayev, who is on a three-day state visit to China.

At the beginning of their official talks, Chinese President Hu Jintao said Nazarbayev was the first foreign head of state to visit China after the country's Lunar New Year festival.

"I believe your visit will inject vitality to the growth of our bilateral ties, and boost our strategic partnership to a new level," Hu said.

Nazarbayev said the current visit was his first foreign trip of 2011, which revealed the close links and friendly tradition between both countries.

The two heads of state witnessed the signing of a series of cooperation agreements on cross-border water resource protection, high speed railway construction, and joint projects on petroleum, oil and gas resources.
