U.S. officials tried to reassure Chinese premier Wen Jiabao about his country’s investment $2 trillion investment in U.S. Treasuries after he expressed worries in the light of the current financial crisis.

“There’s no safer investment in the world than in the United States,” White House spokesman Robert Gibbs said Friday during a press briefing according to Bloomberg.

Jiabao expressed concern about the capital it had invested in U.S. debt, saying he is “worried” about China’s holdings.

“I request the U.S. to maintain its good credit, to honor its promises and to guarantee the safety of China’s assets,” he said in Beijing.

U.S. Treasury spokeswoman Heather Wong told Bloomberg that “The U.S. Treasury market remains the deepest and most liquid market in the world.”
