China Aviation Suppliers Holding Company (CASC) has signed an agreement with Boeing to purchase 300 aircraft for more than $37bn.

The deal includes orders and commitments for single-aisle and twin-aisle aircraft and was signed during US President Donald Trump’s visit to China.

After signing the deal, Boeing Commercial Airplanes president and CEO Kevin McAllister said: “China is a valued customer and key partner, and we’re proud that Boeing airplanes will be a part of its fleet growth for years to come.

“Boeing and China have a strong history of working together based on great mutual respect, and these orders build on that foundation.”

With the latest deal, Boeing also seeks to collaborate with its Chinese counterparts to improve the country’s aviation market.

In a separate development, Boeing and China Development Bank Financial Leasing’s Ireland-based subsidiary CDB Aviation have finalised an order for 60 aircraft, which is valued at $7.4bn at current list prices.

A memorandum of understanding (MoU) of the order was signed at this year’s Paris Air Show held in June.

The order includes 42 737 MAX 8s, ten 737 MAX 10 aircraft and eight 787-9 Dreamliners.

Six of the 737 MAX 8 orders included in the MoU have been converted to 737 MAX 10 order.
