Chinese airlines have ordered 95 Airbus jets in deals totalling more than $17bn, according to company announcements on Friday.
China is a key export market for European aircraft, machinery and cars.
Flag carrier Air China agreed to buy 55 Airbus planes for itself and a subsidiary in a $12.44bn deal, it said in a filing to the Shanghai Stock Exchange.
The Beijing-based operator will take 15 Airbus A350-900 jets and its subsidiary Shenzhen Airlines will get 40 aircraft in the A320neo family, according to its filing.
The planes will be delivered in batches between 2029 and 2032, Air China said.
It added that Airbus had made "significant price concessions" for both airline purchases.
Hainan Airlines, which has one of China's largest fleets, said it had agreed to buy 40 Airbus A320neo aircraft for no more than $5.36 bn in a separate filing to the Shanghai Stock Exchange.
The aircraft are scheduled for delivery between 2028 and 2032, it said.
In April, China Southern Airlines said it ordered 137 single-aisle Airbus A320neo planes for a catalogue value of $21.4bn.
In March, China Eastern Airlines said it signed a $15.8bn deal to buy 101 Airbus A320neo planes.
The European aviation giant aims to deliver 870 commercial aircraft in 2026, which would surpass its record of 863 in 2019.
