Strong tremors were felt in China’s southwestern province of Yunnan, but no casualties have been reported so far, according to state news agency Xinhua.
Other Chinese media outlets reported that many in Yunnan felt the quake, with some injuries and damage to houses. Rescue operations are reportedly under way.
Videos posted on Chinese social media showed buildings shaking in Kunming, the capital of Yunnan.
Associated Press reported that there were no immediate estimates of injuries or deaths from Myanmar, which is embroiled in a civil war.
Energy-rich Myanmar also serves as a strategic overland route for China’s oil and gas imports from the Middle East, reducing reliance on sea routes dominated by the US and shortening transport time.
