Chinese prime minister Wen Jiabao says China will continue to support the crisis-hit eurozone.
During a visit to Britain, Mr Wen said China had increased its investments in government bonds from some EU countries, demonstrating Beijing's continuing confidence in the eurozone.
He also acknowledged that China's massive trade surplus is bad for global stability.
He told the BBC it was a priority to boost domestic demand as well as reduce its foreign trade surplus and reliance on exports.
Up to £1bn worth of business deals are expected to be announced during Mr Wen's three-day UK tour, the BBC said.
Rival groups of demonstrators gathered outside a Chinese-owned car factory in Birmingham that Mr Wen was visiting.
