Mainland Chinese users trying to access Google Translate in China were instead shown a static image of a generic Google search bar, and a link to the company’s Hong Kong–based domain. (Google in Hong Kong is uncensored and blocked to mainland Chinese users.)

The sudden suspension put some Chinese applications, which relied on Google for translation, in a bind, as users reported problems with programs like document reader KOReader, according to TechCrunch, which first reported the suspension.

A Google spokesperson told Fortune that the company had “discontinued Google Translate in mainland China due to low usage.”

Google Translate’s China service received 53.5 million hits from desktop and mobile users combined in August, according to the South China Morning Post, citing data from web analytics platform Similarweb. Google Translate as a whole received 719 million hits over the same period outside of China, according to Similarweb data. 

Google introduced a Chinese mobile app version of Google Translate as a foray back into the China market in 2017, bringing in Chinese-American rapper MC Jin to advertise the service to Chinese users. Users in China could download the app without using a virtual private network to evade the country’s internet controls. At the time, Google said it hoped the service would help mainland Chinese “discover a world without language barriers.”

Google originally offered a censored version of Google Search to mainland Chinese users in 2006, but it faced strong competition from local competitors like Baidu.

In 2010, Google said it would redirect mainland Chinese users to its (uncensored) Hong Kong search engine. The decision to offer uncensored search followed a hack of Google and other U.S. tech companies by actors allegedly connected to the Chinese government. Beijing then blocked Google search in China and has continued to block other Google services like Gmail in the years since.

Google considered bringing a censored search product back to China in 2018 via a project reportedly called Dragonfly, according to the Intercept. Protests from Google employees ultimately scuttled the project.

Google maintains an office in China to support developers and help Chinese companies place Google ads overseas. 

Several Western tech companies, like Amazon, Airbnb, and Yahoo, have shut down services in China over the past year. Others have altered their offerings to comply with new internet regulations in China. Microsoft’s LinkedIn platform, for example, removed the social media feed from its China platform last year, citing “greater compliance requirements.”

Even exercise isn’t safe. Nike suspended its popular Run Club app for Chinese users earlier this year.
