In the 1960s, as the Cultural Revolution was coming into fruition, China and the USSR cut ties. Anyone with connections to the USSR was seen as a potential political enemy. In 1966, Ulanfu due to his previous close connection to the USSR, was to become one of the most senior victims of the Cultural Revolution when he was denounced and dismissed for alleged anti-party activities. He disappeared until after Mao’s death when he was appointed Vice Premier in a wave of rehabilitations of party officials who fell victim to the witch hunts during the Cultural Revolution.
