Maldives - Rejoins

In 1982, Maldives joined the Commonwealth. However, in 2016, the country left it, which was in response to the Commonwealth’s suspension warning. The Maldives’ government claimed that the Commonwealth “sought to become an active participant in the Maldives' domestic political discourse, which is contrary to the principles of the charters of the UN and the Commonwealth.”

Then, on the 1st February 2020, under the Ibrahim Mohamed Solih government, the country rejoined the Commonwealth.
