Which two countries became independent in 1957?

Malaysia and Ghana share similar economic and historic backgrounds. They are both former British colonies and gained independence from the British Empire in the 1957. After gaining independence both countries began with rich resources and sturdy British political and legal institutions, as well as identical educational systems. Why their development levels diverged so much is a big question. Ghana is among the poorest nations while Malaysia is a fast developing country and part of the middle income group of nations.
