The war games in south east China beginning on July 29 is part of the Chinese armed forces' routine training, the Ministry of National Defense said in a statement today.
The drills are important for testing combat capability and improving real-combat training levels and military preparation, it said.
Both military and civil aviation management authorities have taken measures to minimise the exercises' impact on civil flights by opening temporary air routes, allocating protection airspace, and setting down alternative deviation plans, it said in a statement.
The armed forces have been taking measures to cut military activities' influence on civil aviation in recent years and will continue to do so in the future, a state-run Xinhua news agency report said.
Today's statement followed yesterday's announcement of plans to conduct a series of live fire training drills for five days next week in East China Sea where it is locked in a bitter maritime dispute with Japan even as air traffic at Chinese airports went haywire due to ongoing air exercises.
The administration warned ships to stay clear of the region and told authorities to ensure safety during the training, which is scheduled to last from midnight to 6 pm each day.
The exercises hit hundreds of air travellers in eastern provinces with massive delays, the Hong Kong-based South China Morning Post reported today.
The civil aviation regulator issued an orange alert - the second highest in a four-tier system, early yesterday morning for 23 airports, including those in Shanghai, Nanjing, Nanchang, Hefei, Zhengzhou and Wenzhou.
Before the warning was lifted at 5 pm, 85 flights were cancelled at Pudong and Hongqiao airports in Shanghai, the Civil Aviation Administration of China said.
