Today, Gunsan's economy thrives on fishing, agriculture and heavy industry west of the city in the reclaimed area known as the Industrial Zone. GM Korea operates a factory here that assembles the Chevrolet Aveo worldwide and as the Holden Barina in Australia and New Zealand. Near the port, the Tata Daewoo Commercial Vehicle factory produces Daewoo trucks for the domestic and export markets. In the domestic market vehicles are sold under Daewoo brand; the Tata brand name is used for export due to the dilution of the Daewoo brand.
