Chinese Premier Li Keqiang on Thursday congratulated British Prime Minister David Cameron on his re-election and vowed to enhance cooperation with Britain.

In a phone conversation, Li said that China-Britain relations have witnessed new progress in recent years and that he and Cameron have maintained good communication and cooperation through meetings, phone calls and correspondence.

The Chinese Government, Li added, attaches great importance to the relations with Britain, and is willing to work with the new government led by Cameron to inject new impetus to bilateral ties and tackle the challenges presented by the global economic downturn.

He pledged to work with Cameron to strengthen political mutual trust, boost exchanges and dialogue, and carry forward practical cooperation in trade and investment, finance and other fields.

Li invited Cameron to pay an official visit to China this year and attend the annual meeting between the premiers of the two countries.

Cameron thanked Li for his congratulations and invitation and said that Britain-China relations are in a golden era of development.

He said he treasures his close working relationships with Chinese leaders and is willing to enhance communication and cooperation with China to further advance bilateral ties in his new term of office.

Cameron said he looks forward to his visit to China and the annual meeting with the Chinese premier, and expressed the hope that the two countries will deepen practical cooperation in various fields and push forward the free trade negotiations between China and Europe.

Cameron's Conservative Party won general elections on May 7, giving him a second term as British prime minister.
