Ex-US China Ambassador Jon Huntsman on Xi Jinping visit
China's leader-in-waiting, Vice-President Xi Jinping, has met US President Barack Obama at the White House.
Mr Obama pressed Mr Xi on trade and human rights, but also said it was "vital" that Washington maintained a strong relationship with Beijing.
Mr Xi said he hoped his visit would deepen mutual understanding and friendship between the two powers.
The US and China have been at odds over trade, currency and human rights.
Jon Huntsman is a former US ambassador to China and was a candidate for the 2012 Republican presidential nomination.
He spoke to the BBC's Katty Kay about the complex and delicate relationship between the two powers.
