Until now, the U.S. has maintained relations with the Maldives through the U.S. ambassador to Sri Lanka.
Pompeo will be joined by Defense Secretary Mark Esper in New Delhi on Monday and Tuesday for annual talks.
Maldives has re-joined the Commonwealth, bringing the total number of nations in the global organisation to 54, it has been announced.
The change came into effect at midnight on Saturday – just over an hour after the United Kingdom left the European Union.
The Maldives is among a number of small countries where China has invested billions of dollars building highways and housing as part of its Belt and Road Initiative. Through that initiative, Beijing hopes to improve trade and investment flows with much of Asia and parts of the rest of the world.
Preliminary results were expected to come out by early Monday and final results are expected to be announced on Sept. 30, local media reports said.
