BEIJING, Feb 4 (Reuters) - China's anti-monopoly

regulator said on Tuesday it had launched an investigation into

Alphabet's Google, minutes after an additional 10%

tariff on Chinese goods imposed by U.S. President Donald Trump

came into effect.

The statement did not offer any further details on the

investigation.

Google products such as its search engine are blocked in

China, but it works with local partners such as advertisers in

the country.
