China launches an antitrust probe into Google

Google has been accused of violating antitrust law in other countries.

The Chinese government's move to open an antitrust probe into Google is the latest development in a long and tangled relationship that goes back to the early 2000s.

The investigation was one of a flurry of Chinese retaliatory measures announced Tuesday in response to a 10% tariff imposed by U.S. President Donald Trump on imports from China.

Others included tariffs on American liquified natural gas and other products, and the placing of two other American firms on an unreliable entity list that could bar them from investing in China.

Here is a look at Google's history in China and what the antitrust probe could mean for the company:

Google launched the Chinese-language search engine google.cn in 2006. It was censored to comply with Beijing’s laws, and in 2009, was a major search engine in China with about 36% market share.

In 2010, in response to a cyberattack and an increasing unwillingness to comply with censorship rules, Google said it was no longer willing to block search results and shut down its Chinese search engine, redirecting users to its Hong Kong site instead.

Beijing later blocked Google services under its Great Firewall censorship system, including the email service Gmail, as well as the Chrome browser and search engine, making them inaccessible to users in mainland China.
