Uber is already facing regulatory scrutiny in several Asian markets, including in South Korea and Japan. The firm said last month it is suspending its services in the Chinese-ruled territory of Macau from July 22. Any Uber-registered cars that defies the suspension order will be fined and impounded, lawyer Aileen Lizada, a member of the transportation board, told Reuters in a text message. "All these cases involving Uber and for that matter anyone involved in public transportation system has to understand that we need to be in some level of regulation," board Chairman Martin Delgra told reporters at a briefing on Tuesday. Uber is hugely popular in the Philippines and is regarded by its users as more reliable and competitive than the country's outdated public transport services. The suspension led to an outpouring of anger by Filipinos on social media. Uber issued an email to users informing them of the suspension, entitled "we'll be serving you again soon".
