Aw Boon Haw and
Boon Par brothers), in order to list most of the assets of Haw Par Brothers (Private) Limited on the Stock Exchange of Malaysia and Singapore. The shares started to trade in the exchange in November 1969. The listed company made a major
disinvestment in 1970, selling Hong Kong Eng Aun Tong building located in
