The KPPU said neither company has given the agency notice about the merger, but they are allowed to notify authorities 30 days after the transaction. Gojek and Tokopedia did not immediately respond to requests for comment. The combined entity, which will span online shopping, courier services, ride-hailing, food delivery and other services in Southeast Asia's largest economy, will be the biggest privately held technology firm in the region. Ride-hailing and payments firm Gojek and e-commerce leader Tokopedia announced their merge earlier this week into a tech company GoTo in Indonesia's largest-ever deal. JAKARTA, May 20 (Reuters) - Indonesia's anti-trust agency (KPPU) on Thursday said it would scrutinise the multi-billion dollar merger of the country's startups Gojek and Tokopedia to check for potential monopolistic behaviour.
