in October 1990, the Petroleum Authority of Thailand arranged with Petronas to study the feasibility of transferring natural gas from this jointly administered area, through Malaysia to Thailand, by way of an extension of the pipelines laid for the third stage of the Peninsular Gas Utilisation Project. That project was on course to becoming a major element in the postponement of oil depletion. Contracts for line pipes for the second stage of the project were signed in 1989 with two consortia of Malaysian, Japanese, and Brazilian companies. This stage, completed in 1991, included the laying of 730 kilometres of pipeline through to the tip of the Peninsula, from where gas could be sold to Singapore and Thailand; the conversion of two power stations—Port Dickson and Pasir Gudang—from oil to gas; and the expansion of Petronas's output of methyl tert-butyl ether (MTBE), propylene, and polypropylene, which were already being produced in joint ventures with Idemitsu Petrochemical Co. of Japan and Neste Oy of Finland. The third and final stage of the project was to lay pipelines along the northwest and northeast coastlines of the Peninsula and was completed in 1997. Another new venture in 1990 was in ship-owning, since Petronas's existing arrangements with MISC and with Nigeria's state oil company would be inadequate to transport the additional exports of LNG due to start in 1994, under the contract with Saibu Gas. Petronas did not lose sight of the government's commitment to Malaysian self-reliance, and the company's second refinery at Malacca, completed in 1994, with a capacity of , promoted the same policy. The fact that it was built in a joint venture with Samsung of Korea, the Chinese Petroleum Corporation of Taiwan, and Caltex of the United States did not negate the policy, for the subsidiary company Petronas Penapisan (Melaka) had a decisive 45% of equity while sharing the enormous costs of and gaining advanced technology for the project. More to the point, a side effect of the refinery's completion was that Petronas was able to refine all of the crude oil it produced, instead of being partially dependent on refining facilities in Singapore. Petronas, with its policies of promoting self-reliance, helping to develop associated industries, and varying the sources and uses of oil and gas, played an important role in the Malaysian economy as a whole. Under governments which—by current, if not historical, Western standards—were strongly interventionist, the contribution of
