Almost all of Brunei's natural gas is liquefied at Brunei Liquefied Natural Gas (LNG) plant, which opened in 1972 and is one of the largest LNG plants in the world. Over 82% of Brunei's LNG produced is sold to Japan under a long-term agreement renewed in 1993. The agreement calls for Brunei to provide over 5 million tons of LNG per year to three Japanese utilities. The Japanese company, Mitsubishi, is a joint venture partner with Shell and the Brunei Government in Brunei LNG, Brunei Coldgas, and Brunei Shell Tankers, which together produce the LNG and supply it to Japan. Since 1995, Brunei has supplied more than 700,000 tons of LNG to the Korea Gas Corporation as well. In 1999, Brunei's natural gas production reached 90 cargoes per day. A small amount of natural gas is used for domestic power generation. Brunei is the fourth-largest exporter of LNG in the Asia-Pacific region behind Indonesia, Malaysia, and Australia.
