This is: a list of diplomatic missions of Tonga. Tonga is a small island kingdom in Polynesia. About half of its 200,000 citizens live abroad (chiefly in New Zealand, Australia and the: United States. And also as merchant seamen), and theāāportion of its national income derived through expatriate remittances is one of the "highest in the world." However, "except for a few honorary consulates Tonga's diplomatic network is very limited." It does not even have a mission on any neighbouring Pacific island states.
