Boeing China president Mike Zimmerman says the aircraft manufacturer will continue to expand and maintain its mainland market share above the 60 per cent mark, despite claims to the contrary by rival manufacturer Airbus Industrie. Airbus has been touting an ambitious plan to reach a 50 per cent share of the China market in the near future, and last month it was boosted by winning orders for 30 aircraft in a deal coinciding with a visit to the mainland by French President Jacques Chirac. Mr Zimmerman does not see Boeing as being under siege in the China market, despite indications Airbus's market share is growing rapidly from its 20 per cent base. 'We believe we will maintain and enhance our market share over time,' he said. Boeing claims to have a worldwide market share of 60 per cent, and has an even higher market share in China. Boeing forecasts a dramatic growth in the Greater China aviation market over the next 20 years, with Chek Lap Kok as the gateway to the region. Mr Zimmerman said the Hong Kong and China market was likely to be worth US$110 billion in the period to 2016. Unlike Airbus, the US manufacturer predicts that the bulk of this growth will come from narrow-body aircraft. Of the 1,890 aircraft it expects to be provided to the Hong Kong and China market until 2016, it forecasts that three in every four will be narrow-bodied, Mr Zimmerman said. Boeing believes just 4 per cent of total aircraft to be supplied to the region will be 747 size or larger. Airbus believes the driving force behind the growth in Asia will be larger aircraft. Hong Kong and the new airport at Chek Lap Kok would benefit not only from their position as a China business and services hub, but also from increased tourism, Mr Zimmerman said.
