China yesterday vowed its support for the Group of 20 summit in London and co-operation with the rest of the world to ride out the financial crisis, hand in hand with the United States. But Foreign Minister Yang Jiechi, speaking on the sidelines of the annual National People's Congress meeting, was tight-lipped on whether the nation would roll out more financial support to resolve the global crisis, an issue world leaders will scrutinise when the G20 summit convenes next month. 'To continue its stable and rapid economic development is China's biggest contribution to resolve the financial crisis,' Mr Yang said, toeing the line that is repeatedly raised by Chinese leaders faced with high hopes that China can do more. The US is especially eager for China to buy more of its treasury bills to help give momentum to US President Barack Obama's stimulus plan. This topped the agenda during US Secretary of State Hillary Rodham Clinton's recent visit to Beijing. But China has been reluctant. Mr Yang said China would only purchase such foreign securities on the principles of 'stability, mobility and growth'. But he said he hoped the forthcoming G20 meeting, a continuation of the Washington summit in November, would be a success. 'We believe the summit should be able to boost confidence, strengthen co-ordination on macroeconomic policies, stabilising financial markets, and undertaking necessary reforms in the global financial system and regulatory regime,' he said. Mr Yang said President Hu Jintao would hold talks with world leaders including Mr Obama and British Prime Minister Gordon Brown at the summit. 'We are willing to ride through the financial crisis with the US and other countries,' he said, adding that Sino-US relations were off to a good start after Mr Obama's inauguration. Another contribution China has made in face of the crisis, Mr Yang said, was its aid to developing countries, including those in Africa. Mr Yang will visit Washington from tomorrow to Friday to prepare for a summit between Mr Hu and Mr Obama.
