A revised free trade pact between Japan and half of the Association of Southeast Asian Nations entered into force on Saturday, easing the cross-border flow of services and investment. The deal took effect for Japan and five Asean members – Laos , Myanmar , Singapore , Thailand and Vietnam . The five remaining members – Brunei, Cambodia , Indonesia , Malaysia and the Philippines – are set to join after they conclude domestic procedures. Dependent on China? How Japan wants to tackle the coronavirus disruption Asean was Japan’s third-largest trading partner last year after China and the United States , with exports to the bloc totalling 11.58 trillion yen (US$110 billion) and imports worth 11.76 trillion yen, according to finance ministry data. It is a major market for Japanese firms as well as a key link in supply chains, with many companies setting up factories in the region to take advantage of cheaper labour. The original economic partnership agreement with Asean took effect in 2008, becoming Japan’s first multilateral free trade pact. It was focused on eliminating tariffs on goods but provided for further negotiations on services and investment. Those negotiations began in 2010, with a consensus reached at the ministerial level in 2017. Japan said in June it had concluded domestic procedures, clearing the way for the deal to take effect. China, Japan, South Korea agree to continue push for free-trade deal Under the revised pact, the countries are required to maintain transparency in regulating services and not discriminate against foreign investors. It also establishes a dispute settlement mechanism for companies to sue a government for unfair treatment, as well as rules for foreign travellers to enter and stay in the other countries. The rules are especially important for Cambodia, Laos and Myanmar, none of which have bilateral trade deals with Japan. Since signing the deal with Asean in 2008, Japan has pushed forward with other multilateral free trade pacts such as the revised 11-member Trans-Pacific Partnership and an economic partnership agreement with the European Union . Japan is also involved in negotiations for the Regional Comprehensive Economic Partnership , a free-trade pact that would encompass Asean along with other countries including China, South Korea , Australia and New Zealand . Negotiations on the deal, known as RCEP, are set to wrap up within the year, though the withdrawal of India has caused some uncertainty.
