Cultural similarities between Ghana and Nigeria​

Many Nigerians began moving to Ghana after Ghana became the first independent country in the region in 1957. Also in the late 1970s many Ghanaians moved to Nigeria as economic migrants. The relationship became sour for various reasons. Thus, under former Ghanaian president Busia's Aliens Compliance Order, Nigerians among other immigrants were forced to leave Ghana as they made up a significant percentage of Ghana's large undocumented population. The official reason for deportation was failing to comply with the immigration laws of the country. In 1983, Nigeria retaliated and deported up to 1 million Ghanaian and other African immigrants when Ghana was facing severe drought and economic problems. This further strained relations between the two countries.[2] In April 1988, a joint commission for cooperation was established between Ghana and Nigeria.
