Rajaratnam was a strong believer in multi-racialism in Singapore, and when drafting the Singapore National Pledge in 1966 just two years after the 1964 Race Riots, he wrote the words "One united people, regardless of race, language or religion." In the 1980s and 1990s, when the government began implementing several policies to promote the use of "mother tongue" languages and ethnic-based self-help groups such as Chinese Development Assistance Council (CDAC) and Mendaki, Rajaratnam expressed his opposition to these policies which, in his view, ran counter to the vision of establishing a common Singaporean identity where "when race, religion, language does not matter". He advocated for greater racial integration which he felt was still lacking in the country.
