Google is planning to launch a censored version of its search engine in China that will blacklist websites and search terms about human rights, democracy, religion, and peaceful protest, The Intercept can reveal.

The project – code-named Dragonfly – has been underway since spring of last year, and accelerated following a December 2017 meeting between Google’s CEO Sundar Pichai and a top Chinese government official, according to internal Google documents and people familiar with the plans.

Teams of programmers and engineers at Google have created a custom Android app, different versions of which have been named “Maotai” and “Longfei.” The app has already been demonstrated to the Chinese government; the finalized version could be launched in the next six to nine months, pending approval from Chinese officials.

The planned move represents a dramatic shift in Google’s policy on China and will mark the first time in almost a decade that the internet giant has operated its search engine in the country.
