Chicago-based Boeing has plans for a joint venture maintenance centre in Shanghai in which it will hold a controlling stake, but will not actually make aeroplanes in China.
The US aircraft manufacturer will continue to buy components from Chinese suppliers, added Rob Laird, vice-president of China sales for Boeing Commercial Airplanes.
“China is part of our global supplier network. These are business decisions made based on cost, quality and the capability of the supplier,” said Laird. He declined to reveal whether Boeing would increase its purchasing in China in the future.
