After 45 years, ping-pong athletes who took part in a series of historic exchanges between China and the U.S. in 1971 and 1972 reunited at the University of Michigan in Ann Arbor, the first stop on the Chinese table tennis team's visit to the U.S. in 1972. [...] "I'm very excited and joyful to be here and meet my old friends today," said Liang. "If it wasn't for Ping-Pong Diplomacy helping to break the ice between the two nations, there wouldn't be as much exchange and communication between China and the U.S. today."

Every other day or so, Hatem El-Gamasy connects to a news audience nearly halfway around the world, delivering hot takes on American politics, live from New York, but on Egyptian television. When the broadcast ends, he slips out his earpieces, opens the door of his makeshift studio and returns to his day job. Mr. El-Gamasy owns the Lotus Deli in Ridgewood, Queens, a place known for its sandwiches, extensive craft beer selection, and its gracious, friendly owner.

A friendship match is held at the headquarters of the United Nations in commemoration of the China-U.S. Ping-Pong diplomacy, 45 years after the Chinese Ping-Pong delegation came to the UN for the first time, in New York September 15, 2017. In 1971 and 1972, U.S. and Chinese table tennis teams exchanged visit after many years of estrangement and antagonism between the two countries, opening the door for the China-U.S. people-to-people contact.
