The ASEAN Free Trade Area (AFTA) is an agreement by the member nations of ASEAN concerning local manufacturing in all ASEAN countries. The AFTA agreement was signed on January 28, 1992 in Singapore. When the AFTA agreement was originally signed, ASEAN had six members, namely, Brunei, Indonesia, Malaysia, the Philippines, Singapore and Thailand. Vietnam joined in 1995, Laos and Myanmar in 1997, and Cambodia in 1999. The latecomers have not fully met the AFTA's obligations, but they are officially considered part of the AFTA as they were required to sign the agreement upon entry into ASEAN, and were given longer time frames in which to meet AFTA's tariff reduction obligations.
