In the first visit to the United States by a chairman of the Standing Committee of the National People's Congress in 20 years, Wu Bangguo will meet US President Barack Obama in Washington on Tuesday local time.
Climate change is likely to top Wu's agenda, said experts, who noted that frequent congressional exchanges this year will help make the development of the bilateral ties more balanced.

Arriving in Phoenix, Ariz., on Sunday, Wu started his weeklong US tour after visiting Cuba and the Bahamas. He was invited by US Speaker of the House Nancy Pelosi, according to Xinhua New Agency.
