The South Pacific has tens of millions of islands, 26 million square kilometers of water, and 20 opposing countries and autonomous territories. Their population and land area are very different, with Europeans, melanesians, Micronesia and Polynesians living there. Every country has different political systems, including republics and monarchies, and different levels of economic development. This area was finally colonized and finally recognized as independent. Due to the centuries-long colonial and imperialist rule, the colonial economy in this area has formed, with abnormal economic development and single product types. Most countries are dominated by agriculture and underdeveloped industries. Many Pacific island countries have embarked on the road of independence, their political and economic models have changed, and the South Pacific is moving towards internationalization. 1971August, seven countries including Fiji, Tonga, Western Samoa, Cook Islands, Nauru, Australia and New Zealand held a meeting in Wellington, New Zealand, and formally established the South Pacific Forum. Its permanent body is the South Pacific Economic Cooperation Bureau, and its goal is to provide cooperation and consultation among member countries in regional trade, economic development, energy, communication, transportation and tourism. Now the membership is increased to 15.
