Antitrust developments and enforcement activity in South-east Asia: January to June 2026

24 August 2026

In this issue of Competition Law H1 2026, we highlight notable antitrust developments and enforcement activity in South-east Asia which took place in the first half of 2026, including the following:

• Brunei: The Competition Commission of Brunei Darussalam, in its May 2026 notice on price-setting terms, cautioned event organisers and participating vendors of food festivals, pop-up markets, and similar events that setting minimum prices or recommended prices, or imposing other terms that influence how vendors set their prices, may run the risk of infringing the Brunei Competition Act (Chapter 253).
• Indonesia: The Indonesia Competition Commission remained active in the first half of 2026, pursuing delayed merger notifications in the telecommunications, renewable energy, palm oil production, logistics, and industrial equipment sectors, and imposing sanctions and advancing proceedings relating to anti-competitive conduct in the technology, construction, home appliances, airlines, plastic manufacturing, research laboratories, loans, gas, and automotive sectors. Digital markets also remained a key area of enforcement focus, with the Supreme Court’s rejection of an appeal filed by a global technology company.
• Malaysia: The Malaysia Competition Commission (“MyCC”) continued active enforcement, including proceedings against alleged bid-rigging in public procurement and issuing a proposed decision against another alleged cartel. The Competition Appeal Tribunal dismissed appeals against MyCC’s finding of price fixing against a cartel in the poultry sector, and the High Court dismissed a judicial review application by a major technology platform provider and upheld MyCC’s finding of an abuse of dominance.
• Philippines: The Philippine Competition Commission (“PCC”) reviewed 10 mergers across a range of sectors, including freight forwarding and warehousing services, energy production, real estate development, retail, insurance, healthcare, consumer products, and business process outsourcing. PCC also approved a settlement submitted by water refilling station operators after PCC’s investigation found that they had fixed prices for certain water products.
• Singapore: The Competition and Consumer Commission of Singapore (“CCS”) achieved a landmark win with the Singapore High Court allowing CCS’s first-ever appeal to the High Court, and reinstating CCS’s infringement decision against two warehouse service providers. On the merger front, CCS cleared transactions across semiconductor, pharmaceutical, and payments sectors, and accepted commitments to clear a transaction in the electric vehicle charging services sector. CCS also consulted on a proposed joint business agreement in the air cargo sector.
• Thailand: The Trade Competition Commission of Thailand reviewed eight mergers, acknowledging six post merger filings in the automotives, insurance, household appliances, freight forwarding services, and agricultural commodities sectors, and granting two pre-merger approvals, subject to conditions, of companies operating in the automotive and private hospital services sectors.
• Vietnam: The Vietnam Competition Commission (“VCC”) imposed sanctions on undertakings in the electronics, beverages, and e-commerce sectors for engaging in unfair competition practices, where the parties across three cases had provided misleading information to customers about their enterprise, products, and services with an intent to attract customers. On the merger control front, VCC conditionally cleared economic concentrations in the petrochemicals, maritime and logistics, as well as medical-device manufacturing sectors. VCC also sanctioned undertakings for failure to notify VCC of an economic concentration.
