China, the US government's largest creditor, is ''worried'' about its holdings of Treasuries and wants assurances that the investment is safe, Premier Wen Jiabao said.

''We have lent a huge amount of money to the United States,'' Wen said at a press briefing in Beijing today after the annual meeting of the legislature. ''Of course we are concerned about the safety of our assets. To be honest, I am a little bit worried. I request the US to maintain its good credit, to honor its promises and to guarantee the safety of China's assets.''

''China is worried that the US may solve its problems with the fiscal deficit and banks by printing money, which will stoke inflation,'' said Zhao Qingming, a Beijing-based analyst at China Construction Bank Corp., the country's second-biggest lender. ''If the US can make sure this won't happen, then China will continue to invest.''
