BEIJING (AP) — China says it has set up alternative flight routes to minimize delays related to military exercises along its southeastern coast that start Tuesday.

A Defense Ministry statement said the exercises were part of regularly scheduled drills aiming to improve the military’s ability to operate under simulated war conditions.

It gave no details about where exactly they would take place, but said officers had been dispatched to regional airports to facilitate the shifting of civilian flights to alternative routes to reduce the impact on travelers.

China’s Civil Aviation Administration warned last week that flights could be disrupted across a wide swath of eastern China through mid-August.

More than 100 flights at Shanghai’s two international airports were delayed or canceled on July 14, prompting rumors that war games were the reason.
