Chisumulu Island (4,000 inhabitants) is the smaller of two inhabited
islands in Lake Malawi (being Likoma Island the larger one). Both these
islands lie just a few kilometres from Mozambique, and are entirely
surrounded by Mozambican territorial waters, but belong to Malawi. They
are therefore exclaves of Malawi. This came about because the islands
were colonised by Anglican missionaries spreading east from Malawi,
rather than by the Portuguese who colonised Mozambique.
