German Chancellor Angela Merkel concluded on Saturday her three-day visit to China with no concrete promise from Chinese government, while Premier Wen Jiaobao said China will make more efforts to help in Europe's debt issues.

China may offer rescue funds to Europe, but has neither the intention nor the ability to buy up Europe, Premier Wen stressed on Friday, in response to concerns over the country's increasing investment in bogged eurozone economies.
