Summary
US President Barack Obama met with Chinese President Hu Jintao at the start at the start of a 47-nation nuclear security summit in Washington, DC.The talks are expected to help determine whether China is prepared to join Western powers in a new round of UN sanctions on Iran over its nuclear program. Tehran says its ambitions are peaceful and it does not intend to build a weapon. Hu's agreement to attend was perceived as a positive sign in Washington after US-Sino relations were strained by issues like China's currency. Diplomats believe China might be willing to join the latest Iran sanctions push but it was still unclear how far Beijing would go to penalize a country with which it has significant economic ties. Iran has already dismissed the US summit and said it would not be swayed by any decisions made at the summit.
