China-U.S. sister city cooperation

In a recent letter to the 5th China-U.S. Sister Cities Conference, Chinese President Xi Jinping said these links have been instrumental in bringing together people at grassroots level. There are 284 pairs of sister provinces, states, and sister cities between China and the United States since diplomatic ties were established between the two countries in 1979. In this special edition of The Point, host Liu Xin visits Long Beach in Los Angeles, a sister city with Qingdao in east China. The cities have been paired since 1985. How much has Long Beach benefited from this relationship? How has that link been maintained, especially during the past few tumultuous years? What potential is there to further tap into?
