Kenyatta and his government were anti-communist, and in June 1965 he warned that "it is naive to think that there is no danger of imperialism from the East. In world power politics the East has as much designs upon us as the West and would like to serve their own interests. That is why we reject Communism. " His governance was often criticised by communists and other leftists, some of whom accused him of being a fascist. When Chinese Communist official Zhou Enlai visited Dar es Salaam, his statement that "Africa is ripe for revolution" was clearly aimed largely at Kenya. In 1964, Kenyatta impounded a secret shipment of Chinese armaments that passed through Kenyan territory on its way to Uganda. Obote personally visited Kenyatta to apologise. In June 1967, Kenyatta declared the Chinese Chargé d'Affairs "persona non grata" in Kenya and recalled the Kenyan ambassador from Peking. Relations with the Soviet Union were also strained; Kenyatta shut down the Lumumba Institute—an educational organisation named after the Congolese independence leader Patrice Lumumba—on the basis that it was a front for Soviet influence in Kenya.
