Then in 1989 ( which came after 1955 in a linear timeline '), ''a peace treaty was successfully and happily concluded, also verifiably on earth, 'between the Government of Malaysia and CPM. The CPM also signed another peace treaty with the Thai Government. ''Both peace treaties were signed publicly on '2 December 1989 in Haadyai, Thailand.
