                                                              Mitsui & Co., Ltd.


                       ACQUISITION OF TANGGUH LNG INTEREST


Mitsui & Co., Ltd. ("Mitsui"), headquartered at 2-1, Ohtemachi 1-Chome,
Chiyodaku, Tokyo, Japan, is pleased to announce that its wholly-owned subsidiary
Mitsui Indonesia Gas B.V. ("MIG"), a company organized and existing under the
law of the Netherlands, has entered into a Sale and Purchase Agreement ("SPA")
for the acquisition of its 50% interest in the Muturi Production Sharing
Contract ("PSC") in West Papua, Indonesia.

MIG signed an SPA on December 1st, 2003 to acquire the interest from BG
International Limited, a wholly-owned subsidiary of BG Group plc. The 50%
interest in Muturi PSC corresponds to an approximately 10.7% interest in the
Tangguh LNG Project. The sale consideration is about US$236 million in cash.
Completion of this transaction is conditional mainly on the waiver of
pre-emption rights by the other Muturi PSC participants and Indonesian
governmental approvals.

Energy resource development is one of Mitsui's strategic priorities, and this
deal is in line with its objective to acquire additional assets.

Outline of the Tangguh LNG Project
The Tangguh LNG Project comprises integrated development of an LNG facility
supplied by large gas reserves from a number of fields located in Muturi, Berau
and Wiriagar field in West Papua, Indonesia. Estimated reserves of natural gas
are approximately 14.4 trillion cubic feet. The commencement of commercial LNG
production is scheduled to begin in 2007. At the peak, the facility will produce
10.5 million tons of LNG. Existing shareholders are BP, CNOOC, Mitsubishi /
INPEX, Nippon Oil, Kanematsu, and Nissho Iwai / Sumitomo.
