China's Vice Finance Minister Zhu Guangyao demanded the US government take "concrete steps" to resolve the fiscal cliff issue and prevent a treasury bond default, the latest warning from the biggest holder of such assets two days ahead of the debt ceiling deadline.

Zhu made the comments at a media briefing held in Beijing Tuesday.

He also urged the US side to accept its responsibility to uphold the stability of international financial markets.

"In the long run, the US must address the fiscal stalemate, must raise the cap of the debt limit soon so as to keep the promise of not defaulting on its Treasury bonds and keep the sound momentum of the US economy and avoid dragging down the world economy," he said.
