Western social media websites like Facebook and Twitter are blocked by China's censors, which has helped drive up the popularity of home-grown messaging app WeChat, owned by Tencent and microblogging service Weibo.
The app is Colorful Balloons and is for photo-sharing.
The app has been created to collate photos from the photo albums of smartphones and share them. The company is registered in Beijing and with no trace of affiliation with US based Facebook.
That indicates she likely is associated with the social media giant.
A source close to the matter confirmed a New York Times report on Friday that Facebook took the unusual step of creating an app called Colorful Balloons and releasing it through a local company with no hint that the social network was involved.
Neither Facebook nor Jingmei has issued any official statement regarding their partnership.
Facebook chief and co-founder Mark Zuckerberg has made high-profile visits to China and met with political leaders there, and is even studying Mandarin.
The secretive approach of launching the app could cause additional difficulties for Facebook with the government of China that maintains strict oversight as well as control over tech companies outside China.
China's internet censorship has left big players like Facebook, Apple and Google out of the huge Chinese market with an audience of more than 700 million internet users.
