US may seek China's aid over Iran

US Treasury Secretary Timothy Geithner starts a two-day visit to China today. Trade tensions have been high between the world's two biggest economies but there's a new item high on the agenda - Iranian oil.

China is the biggest buyer of Iranian crude. And according to reports, the US may try get its support in sanctioning Tehran's exports to curb its nuclear ambitions.
