This is a traditional Polynesian economy in which more than 90% of the land is communally owned. Economic activity is strongly linked to the US, with which American Samoa conducts most of its foreign trade. Tuna fishing and tuna processing plants are the backbone of the private sector, with canned tuna the primary export. Transfers from the US Government add substantially to American Samoa's economic well-being. Attempts by the government to develop a larger and broader economy are restrained by Samoa's remote location, its limited transportation, and its devastating hurricanes. Tourism, a developing sector, has been held back by the recurring financial difficulties in East Asia.
