Lithuania underwent rapid industrialization during the Soviet era and has significant capacity in machine building and metalworking, as well as the textile and leather industries, and agro-processing (including processed meat, dairy products, and fish). The country's diverse manufacturing base also includes an oil refinery and high-tech minicomputer production. Other industrial products include refrigerators and freezers, electric motors, television sets, metal-cutting machine tools, small ships, furniture, fertilizers, optical equipment, and electronic components. Due to a rapid program of privatization, more than 80% of Lithuania's enterprises are privately owned. Most capital investment has gone into the industrial sector. Major infrastructure projects were planned in 2002, including upgrading the oil refinery, the nuclear power plant, construction of a main highway, and the modernization of sea-port facilities. The industrial sector accounted for about 31% of GDP in 2001.
