BEIJING, Feb 4 (Reuters) - China said on Tuesday it had

launched an anti-monopoly investigation into Alphabet's

Google and added two U.S. firms to its "unreliable

entity list," minutes after additional U.S. tariffs on Chinese

goods came into effect.

The measures were announced as Beijing also slapped tariffs

on some U.S. products such as coal and oil in a rapid response

to the new U.S. duties on Chinese goods, and mark escalating

trade tensions between the world's two biggest economies.

China's Commerce Ministry said it had put PVH Corp ( PVH ),

the holding company for brands including Calvin Klein, and U.S.

biotechnology firm Illumina ( ILMN ) on its unreliable entity

list.

It said the two companies took what it called

"discriminatory measures against Chinese enterprises" and

"damaged" legitimate rights and interests of Chinese companies.

Separately, China's State Administration of Market

Regulation said Google was suspected of violating the country's

anti-monopoly law, and it had initiated an investigation into

the company in accordance with the law. It did not offer any

further details on the investigation or on what it alleged

Google had done to breach the law.

Google products such as its search engine are blocked in

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

the country.

Google, PVH and Illumina ( ILMN ) did not immediately respond to

requests for comment outside regular U.S. business hours.
