Tonga's economy is characterized by a large nonmonetary sector and a heavy dependence on remittances from the half of the country's population that lives abroad, chiefly in Australia, New Zealand, and the United States. Much of the monetary sector of the economy is dominated, if not owned, by the royal family and nobles. This is particularly true of the telecommunications and satellite services. Much of small business, particularly retailing on Tongatapu, is now dominated by recent Chinese immigrants who arrived under a cash-for-passports scheme that ended in 1998.
