Two cities join hands through links with Xi Jinping

The small Iowa city of Muscatine welcomed special guests from Zhengding county, Hebei province, on Monday.

The Chinese delegation of eight led by Mayor Yang Lizhong had a mission: sign a sister-city agreement with Muscatine.

"It is exciting, and in a lot of ways it is our contribution to world peace," said Muscatine Mayor DeWayne Hopkins.
