In 1971, the
Senkaku Islands dispute arose. The administration of the
Senkaku/Diaoyutai Islands was transferred from the
United States to
Japan. On 14 February 1971, the Hong Kong Action Committee in Defence of the Diaoyutai Islands was established(). The Action Committee held demonstrations in front of the Japanese consulate in Hong Kong. Twenty-one people were arrested, seven of whom were university students. On 17 April, the
Hong Kong University Students' Union held a peaceful demonstration involving about 1000 students. On 7 July, the HKFS held a demonstration on a larger scale. In 1971, the HKFS was an illegal organisation and some students were arrested by the
Royal Hong Kong Police. On 13 May 1975, the federation held its last protest over the issue. During 1975 and 1976, the standing committee of the HKFS voiced its support for the
Cultural Revolution in mainland China. The committee criticised Mak Chung Man, who led students to protest against the communists and said he was "against all the Chinese". Students resented this statement and the issue became the main topic of debate during the HKFS elections of 1976. In April 1977, the Hong Kong University Students' Union suggested the removal of the words "anti-right wing" from the action guide of the HKFS but the standing committee refused to vote. All delegates from the Hong Kong University Students' Union withdrew from the HKFS in protest. In April 1979, the HKFS commemorated the
May Fourth Movement. The event was poorly attended. ==1980s and 1990s==
