Relations extended in leaders' meeting

Few meetings between the heads of the world's two largest economies range in content from chitchat to covering complicated issues such as Middle East upheavals and nuclear crises.

But this was what took place over 100 minutes when President Hu Jintao met US President Barack Obama on Tuesday on the sidelines of the Seoul Nuclear Security Summit.

The meeting began with both leaders noting that this was their 11th meeting in three years. That showed the importance their countries place on US-China relations, Obama said, adding that he was looking forward to a "constructive, frank and productive" meeting in which he would discuss economic and commercial issues and look to expand trade.
