The nearly 740-page document, which was laboriously negotiated for two years, was agreed, after unfortunate negotiations, to the finer details of a financial services and double taxation prevention agreement, which did not allow Indian companies registered in Singapore to realize capital gains. It was signed on 29 June 2005.  Singapore and India completed the second revision of the India-Singapore Comprehensive Economic Cooperation Agreement (CECAF) on 1 June 2018, in the presence of Indian Prime Minister Narendra Modi and Singapore Prime Minister Lee Hsien Loong.  It allows the movement of four types of businessmen between Singapore and India. The second revision of the C.A.C.A. was completed without any amendment to the chapter on the free movement of persons. .
