Tuesday marks the fifth anniversary of a landmark symposium on improving the development of the Yangtze River Economic Belt, the first of its kind, chaired by Chinese President Xi Jinping.
At the meeting held in Southwest China's Chongqing Municipality, January 5, 2016, Xi stressed ecology and "green development" in boosting the growth of the Yangtze River Economic Belt.
The Yellow River and the Yangtze River, the two longest rivers of China that run west to east across the nation, are both known as "cradles of Chinese civilization."
Home to about 900 million residents, or 60 percent of the country's total population, the regions along the two rivers are major contributor to the country's economic growth.
Over the last several years, President Xi has visited the two rivers multiple times and left instructions to boost green and high-quality development of the regions by the rivers.
What changes have taken place in the rivers and to the people who live near them?
Let's follow former CBS newsman Brian Linden, who has lived in China over 20 years, for answers.
