US President Barack Obama said China could have "absolute confidence" in the US economy after Chinese government officials questioned the safety of their investments in the US, AFP reported. "Not just the Chinese government, but every investor can have absolute confidence in the soundness of investments in the United States," Obama said on Sunday. Obama was responding to pointed comments from Beijing about the health of the US economy. China’s Premiere Wen Jiabao on Friday said he was "a little bit worried" about the safety of China’s investment in the US. "We have lent huge amounts of money to the United States. Of course we are concerned about the safety of our assets," Wen told reporters in a press conference that drew the National People’s Congress to a close. China held US$727.4 billion in US Treasury bonds at the end of last year, making it America’s largest creditor.
