BOC and Sinopec SPC to form industrial gases joint venture in Shanghai


Windlesham, UK, 3 June, 2004 - BOC (LSE: BOC), the leading industrial gases
supplier in Asia, and Sinopec Shanghai Petrochemical Company Ltd. (SPC), a
subsidiary of Sinopec Corp., have signed a letter of intent to form a joint
venture (JV) to meet the industrial gases needs of SPC in the Jinshan District,
Shanghai, China.


The JV expects to invest initially in the production of nearly 3,000 tonnes per
day of air separation gases capacity through the acquisition of SPC's existing
industrial gases assets and then to commence construction of a new world-scale
air separation unit (ASU).


The scale economics of the project, with its reliable, multi-plant arrangement,
will result in the JV becoming a major industrial gases supplier in the region.
The JV will support SPC's fast growing petrochemical business and those of
additional customers in the area. The Jinshan District where the JV will be
located is one of the major areas of petrochemical investment in China and,
aside from the SPC complex, includes the nearby Shanghai Industrial Chemical
Park, where a number of global and local chemical companies are located.


The JV will be the second industrial gases venture that BOC has entered into
with a Sinopec company. In April 2002, BOC and Sinopec Yangzi Petrochemical
Corp. (Sinopec YPC), a subsidiary of the Sinopec Group, formed a joint venture
known as Nanjing BOC-YPC Gases Company Ltd. (BYG) to meet expanding



                                                                   Page 3 of 11



industrial gases requirements in Nanjing, China. BYG has entered into long-term
supply agreements with two major industrial gas users in the area, the large YPC
Petrochemical Co. Ltd complex and the BASF-YPC Company Ltd integrated
petrochemical complex, both located in the Nanjing Chemical Industry Park.


Mr. Wu Hai Jun, deputy general manager, Sinopec Shanghai Petrochemical Co., Ltd
said: "By co-operating with BOC - an international and professional gas company
- to supply utilities and infrastructure services, SPC will be able to focus
more on developing and enhancing the competitiveness of its core business in the
petrochemical industry. The co-operation not only benefits SPC in terms of
production cost reduction and business profitability but also allows us to
supply customers in the adjacent areas with gas products that will deliver
attractive returns for both partners."


Steven Fang, global vice president, BOC Process Systems, said: "We are delighted
to be able to extend our partnership with Sinopec through this second JV and
further strengthen our position as the leading industrial gases supplier to the
petrochemical industry in China. We are very confident that this JV, like our
current partnership in Nanjing, will leverage both parties' resources and
capabilities to optimize plant operations in support of Sinopec's petrochemical
business and other major investors in the region."


SPC, Sinopec Corp.'s largest subsidiary, was the first Chinese company listed on
the New York, Hong Kong and Shanghai stock exchanges. It is one of the largest
petrochemical companies in China, producing refined oil products, intermediate
petrochemicals, synthetic fibres and plastics. It is also the largest ethylene
and acrylic fibre producer, and one of the most important producers of oil
products, resins and synthetic fibres in China.


The BOC Group (LSE:BOC), the worldwide industrial gases, vacuum technologies and
distribution services company, serves two million customers in more than 50
countries. It employs 44,500 people and had annual sales of some (pound)4.3
billion in 2003.




                                                                   Page 4 of 11


BOC was the first global industrial gases company to establish a presence in
China and has invested more than US$400 million over the past two decades. In
addition to its joint venture relationship with Sinopec, BOC has recently
initiated important capacity expansions with Taiyuan Iron and Steel Corporation
(TISCO), the largest stainless steel producer in China; and Guangzhou Iron and
Steel (GIS), a major steel producer in China with an annual steel production
capacity of 3.5 million tons.

BOC supplies gas and related solutions to the chemicals, petroleum, glass, water
services, electronic packaging, fibre optics, hydrogen energy, metals and food
industries. BOC helps meet customer needs in a variety of ways, from the supply
of a single gas or application through to designing, constructing and operating
fully integrated gas and utilities schemes. Further information about The BOC
Group may be obtained on the Internet at www.boc.com.
