"These initiatives will make us individually and collectively a much stronger source of LNG supply with the added security of LNG plants in different locations in the region and a fleet of 25 LNG ships," said Petronas chief executive, Hassan Marican.
The three countries, which produce two-thirds of the world's LNG, are facing slowing sales growth as demand from Japan - the world's top LNG importer - is falling due to a prolonged recession in that country.
"We talk about customers requesting flexibility in a changing LNG business environment," Mr Hassan told reporters at the Brunei Gasex 2002 conference. "One of the things that for a long time has been ignored is co-operation between LNG producers in this region."
Mr Hassan pointed to the example of how his company helped Indonesia's PT Arun LNG plant with gas shipments to Arun's customers after attacks by separatist rebels halted ExxonMobil gas production.
