Former U.S. secretary of state Henry Kissinger on Saturday called for China and the U.S. to cooperate. The remarks are part of footage released from the China Development Forum, an annual international meeting in Beijing where global business and government leaders discuss topics of importance. 96-year-old Kissinger played a pivotal role in thawing of China-U.S. relations in the 1970s, laying the groundwork for former U.S. president Richard Nixon's historic visit to China in 1972.
