What is the distance between SIngapore and Sudan?

However, many new states were plagued by what Westerners describe as "tribalism", rivalry between ethnic groups within the nation. This sometimes resulted in their near-disintegration, such as the attempt by Biafra to secede from Nigeria in 1970. In Asia, the disintegration of Pakistan into Pakistan and Bangladesh is another example where ethnic differences, aided by geographic distance, tore apart a post-colonial state. The Rwandan genocide and recurrent problems experienced by the Sudan can also be related to a lack of ethnic, religious, or racial cohesion within the nation. It has often proved difficult to unite states with similar ethnic but different colonial backgrounds. Whereas successful examples like Cameroon do exist, failures like Senegambia Confederation demonstrate the problems of uniting Francophone and Anglophone territories.
