Premier Wen Jiabao said on Friday he was "a little worried" about the safety of Chinese assets in the United States, and urged the US government to ensure the security of those assets.

Wen noted that Beijing was the US' biggest foreign creditor and asked Washington to ensure that its response to the global slowdown did not damage the value of Chinese holdings.

"We've lent a huge amount of capital to the United States, and of course we're concerned about the security of our assets. And to speak truthfully, I am a little bit worried," said Wen at a press conference after the close of the annual parliament session.
