Ride-hailing service Uber could be banned in Taiwan after authorities accused it of operating illegally, with officials saying a final decision will be handed down next week.

It is the latest setback for the US company, after it was forced to suspend its operations in Hungary last month and was fined in June for operating illegally in France.

Uber entered the Taiwan market in 2013 and the company and drivers together have already been fined a total of Tw$65 million (€1.83m), according to the transport ministry.

Angry taxi drivers surrounded the parliament in capital Taipei last month, demanding the government kick Uber out, echoing similar protests in several other countries.

Authorities say Uber does not have the proper registration to operate as a taxi service.

"They (Uber) are registered as an information services provider, but what they're doing is actually transportation," said Lin Kuo-hsien, a ministry spokesman.

That leaves consumers unprotected, Lin said, adding that some Uber drivers have already had their individual licences suspended and are subject to fines of Tw$50,000.

Taiwan's investment commission, which screens and approves foreign and outward investments, said Wednesday it would decide on Uber's case by 11 August.

"From a preliminary assessment, it is possible" Uber will be banned, Emile Chang, executive secretary of the commission, told AFP news agency.

"It is what the Ministry of Transportation recommends. However, we have yet to come to a final conclusion," he said, adding that Uber could appeal any decision.

Uber did not respond to a request for comment.

The US start-up has expanded to more than 50 countries and is worth some $50 billion, but has faced multiple legal challenges and protests from traditional taxi drivers who feel they are being forced out of the market.

Uber announced it was suspending business in Hungary in June, saying new legislation made it "impossible" to operate. The fines in France followed violent protests by established taxi drivers.

In China, Uber agreed on Monday to tie up with ride-sharing giant Didi Chuxing, ending a ferocious battle between the two.

Didi Chuxing will take over Uber's China operations in exchange for a stake in the Chinese ride-sharing giant, with the combined firm expected to be valued at $35 billion, according to Bloomberg News.
