Malaysia's state oil and gas firm Petroliam Nasional Berhad (Petronas) wants to extend its long-term contracts with Japanese customers to supply liquefied natural gas (LNG), a company executive said on Friday.

Speaking online at a press conference in Tokyo, vice-president of LNG marketing and trading Shamsairi Ibrahim also said that Petronas would like to sell more LNG to Japan, which was the world's top importer of the chilled fuel last year.
