WASHINGTON (Reuters) – Alphabet Inc’s Google unit has told U.S. lawmakers it is considering “a variety of options” for offering additional services in China.

The company has come under criticism after reports it is considering re-entering the Chinese search engine market and would agree to comply with China’s internet censorship and surveillance policies.

In an Aug. 31 letter to senators made public on Friday, Google CEO Sundar Pichai said the company is “thoughtfully considering a variety of options for how to offer services in China in a way that is consistent with our mission.” Google declined to comment Friday on the letter.
