China has promised to help resolve the eurozone debt crisis, after talks with EU leaders in Beijing.
But Premier Wen Jiabao has made no specific promise to invest in a European bailout fund.
EU leaders have been seeking Chinese money to help bolster a fund of about 500 billion euros ($US665 billion).
The BBC reports Europe is China's biggest trading partner, with trade worth 560 billion euros flowing between the two last year.
In a joint news conference with European Council President Herman Van Rompuy and European Commission President Jose Manuel Barroso, Mr Wen said China was willing to ''increase its involvement'' in attempts to stabilise the eurozone.
''China is firm in supporting the EU side in dealing with the debt problems. We match our words with our actions,'' he said.
''We are willing to conduct close communication and co-operation with the EU side.''
But he offered no specific investment.
