Trump says US will examine Peter Thiel's claims of Google's ties with China

President Donald Trump said Tuesday he wants his administration to "take a look" into whether Google has been working with the Chinese government -- an allegation swiftly denied by the US internet giant.

Trump echoed an unsubstantiated remark from tech billionaire Peter Thiel that Google had been working with China's government or military establishment.

"Billionaire Tech Investor Peter Thiel believes Google should be investigated for treason," Trump said in a tweet.

"A great and brilliant guy who knows this subject better than anyone! The Trump Administration will take a look!" Google said the allegations were baseless and questioned the motives of Thiel, a longtime Trump supporter who is on the board of tech rival Facebook.

"As we have said before, we do not work with the Chinese military, " Google said in a statement to AFP.

Google pulled its search engine from China in 2010 to protest efforts by Beijing to censor its search results. It recently began researching a modified version of its search engine for China but said it had no plans to deploy it.

Trump has assailed Google on several occasions, claiming "bias" against him and his supporters.

Earlier this year, he criticized the tech giant for withdrawing from the bidding from a large Pentagon computing contract, but later softened his tone after meeting Google chief executive Sundar Pichai.

Google has limited business operations in China, but one report this year said one of its scientists participated in a research project that could have both civilian and military applications.
