China's civil aviation authorities have ordered all 28 Chinese round-trip flights that typically fly over that airspace to avoid eastern Ukraine.
That follows a similar notice issued by the Federal Aviation Administration of the United States.
Earlier, Turkish, French, Russian, and British airlines all issued similar announcements.
The Malaysia jetliner is not the only one that had been shot down over the risky airspace.
Back in 2001, the Ukrainian military accidentally shot down a Russian civilian plane during a military exercise.
All 78 passengers and crew died.
Back in 1988, an American missile cruiser shot down an Iranian passenger plane headed to Dubai over the Persian Gulf.
It mistook the civilian plane for a fighter jet, and killed all 290 people on board.
In 1983, a Korean Airlines flight veered from its usual flight path from New York to Seoul.
It was shot down by the air force of the Former Soviet Union, which mistook the jet for a US spy plane.
And in 1973, a Libyan civilian plane drifted into Israeli airspace due to extreme weather conditions.
It was then shot down by the Israeli air force.
Israeli authorities said the plane had been mistaken for an Egyptian MIG fighter jet.
About 108 people were killed in that accident.
