* Higher trade seen benefiting commodities exporters
* Developing nations add more to 2010 world exports (Updates with comments, Chile and Mexico export expectations)
SANTIAGO, Sept 2 (Reuters) - Trade with Latin America and the Caribbean will surge in 2010, with exports seen rising 21.4 percent from a year earlier and imports up 17.1 percent as the region bounces back from global crisis, the United Nations economic body for Latin America said on Thursday.
The region's more dynamic domestic demand, rising investment and exports on the back of growing demand from Asia and the United States are helping trade take off this year.
"The best performance is seen in countries that export raw materials, while the recovery is slower in countries that import basic products and are dependent on tourism and remittances," the report said.
Chile, the world's top copper producer, is expected to increase exports by 32.6 percent in 2010 from the previous year, while Mexican exports are seen up 16 percent.
Developing nations will contribute more than industrialized nations to world export growth in 2010 after a fall in exports last year, the report said. (Reporting by Antonio de la Jara; Writing by Simon Gardner, editing by Todd Eastham)
