The Grab acquisition of Uber’s Southeast Asia operations hasn’t quite made a full transition. Originally, the deal – which was announced last month – was to have seen Uber’s ride-sharing and food delivery business integrated into Grab’s existing platform in eight regional markets on April 8, with Uber deactivating its app then.

The transition hasn’t been completed – while Uber shut down its business in Indonesia, Thailand, Vietnam, Cambodia, Myanmar and Malaysia on schedule yesterday, it remains operational in Singapore and Phillipines under the order of local authorities, which are reviewing the deal.

In Singapore, the country’s competition watchdog is looking into the merger, The Straits Times reports. The Competition and Consumer Commission of Singapore (CCCS) said it believes aspects of the deal infringes the Competition Act, and demanded that Uber remaining operational until April 15 as it decides on its next move.

The CCCS has also proposed interim measures to preserve competition as it continues investigating. These include making Grab and Uber maintain independent pricing, pricing policies and product options as they were before the sale. If these measures are imposed, both companies would not be able to take action leading to the integration of the businesses in the republic, the report added.

Meanwhile, in the Philippines, the country’s anti-trust regulator has done the same thing. Over the weekend, the Philippine Competition Commission said both companies should keep their operations separate and refrain from making further moves toward completing the transaction as it reviews the deal, the Nikkei Asian Review reported.

Again, interim measures are being imposed, though here it’ll apply well past mid-April. The PCC said that Uber’s app should remain accessible to passengers during the course of the review. Though the order didn’t indicate a deadline, this could take as long as 195 days, depending on the findings of regulators.

The commission said it rejected Grab and Uber’s arguments, which said that interim measures laid down by the PCC were unnecessary – Uber said that it had already effectively left the region and lacks the manpower and resources to operate.

Grab, meanwhile, had said there are plenty of transport options in the country. In its argument, it said that new competitors will still be able to enter the Philippine ride-hailing business, of which 80% of these is likely to be controlled by Grab once the deal closes.

The primary reservations about the deal concerns its potential development into a monopoly, which could lead to fare hikes as well as lower incentives for drivers.

In Malaysia, the government has said that it has yet to run any investigations on Grab, as the e-hailing service provider has not committed any offence under the Competition Act 2010, The Malaysian Reserve reports. Minister in the prime minister’s department Datuk Seri Nancy Shukri said the government is convinced that the merger will not affect the local e-hailing scene, but added that it would take action if there are any wrongdoings.

“At present, there is nothing to investigate. We have alerted our officers to monitor complaints on any fare hike or any other wrongdoings,” she told the publication last week.

The cost of Grab’s purchase of Uber’s SEA business was not disclosed, but Uber will be given a 27.5% stake in Grab and Uber CEO Dara Khosrowshahi will join Grab’s board.
