JAKARTA — Southeast Asia is bucking the global trend of falling direct foreign investment, as the low-cost fast-growing region solidifies its position as an attractive location for multinationals. James Dyson’s recent decision to relocate the headquarters of his eponymous technology business to Singapore is not about Brexit, the company said. Rather, the British tycoon said he is looking to a region that continues to exhibit solid growth — “future proofing” as his chief executive termed it. The move follows an October announcement that Dyson — famous for its vacuum cleaners — will make electric vehicles in Singapore, citing the city-state’s proximity to “high-growth markets” in emerging Asia, where annual gross domestic product could grow by 6.1% between now and 2023, according to the Organization for Economic Cooperation and Development. Asia received a third of global investment in 2018 and accounted for nearly all the year’s investment growth, according to the United Nations Conference on Trade and Development. This is despite global foreign direct investment (FDI) declining 19% in 2018. Japanese retailer Aeon opened a second large mall in Cambodia in June as part of its regional expansion plans, which this year will include new shopping centers in Hanoi and Bogor, Indonesia. “As for South East countries, generally speaking, they have been showing rapid economic growth and will keep their pace in future, too,” an Aeon Asia spokesperson said.
