Ethnic tension continued to grow shortly after Mahathir narrowly defeated Tengku Razaleigh Hamzah for the UMNO Presidency in 1987. Around this time, several deposit-taking co-operatives (DTCs), some associated with the MCA, collapsed. To save Chinese investors, the MCA asked the government to bail out the DTCs, citing a previous bailout of Bumiputra financial institutions. UMNO's reluctance to acquiesce led MCA Deputy President Lee Kim Sai to warn that the MCA might quit the government. Later that year, the government posted several non-Chinese-educated staff to senior positions in Chinese vernacular schools. Anwar Ibrahim, then Education Minister, refused to yield to protests from the MCA, and stated that the decision was final, despite a previous informal agreement on the issue between the Malay and Chinese communities.
