Many significant breakthroughs in China-Britain relations as well as in China-Europe relations have been made over the past five days, Wang said.

Earlier on Friday, China and Britain issued a joint declaration on building a "global comprehensive strategic partnership for the 21st century."

The minister commended that the new definition of bilateral ties reflects both countries are enthusiastically expecting to achieve win-win cooperation with each other.

In the declaration, the two sides pledged joint efforts in fields ranging from RMB internationalization and the free trade talks between China and the European Union to cyber security and climate change.

The two sides also vowed to enhance bilateral trade and investment and strengthen political trust based on equality and mutual respect.

Britain "welcomes the progressive participation of Chinese companies in its civil nuclear energy projects," says the declaration, issued one day after Chinese and French companies signed an agreement to cooperate in the building of a nuclear power plant at Hinkley Point in southwestern England.

All the agreements have brought the bilateral ties up to a new level. The declaration has pointed out the new directions for the long-term comprehensive cooperation between China and Britain and offered a beautiful blue print for bilateral ties, Wang added.
