Korean Companies in Southeast Asia — 2026-10-21
Top developments
SK-Affiliated Firms Inject $62 Million into Phu Tho
Two South Korean component manufacturers, including a member of the SK Group, have recently invested more than $62 million in Phu Tho province, Vietnam. This capital injection reinforces the trend of major Korean conglomerates deepening their supply chain footholds in northern Vietnam’s industrial zones, particularly in electronics and precision parts manufacturing.
Anam Electronics Plans New Factory in Hung Yen
Anam Electronics Vietnam, a company with 100% South Korean foreign direct investment (FDI) capital, is considering expanding its production capacity by building a new factory in an industrial park developed by Viglacera in Hung Yen province. This move highlights the continued preference of Korean SMEs for northern Vietnamese industrial hubs like Hung Yen and Bac Ninh for electronics assembly.
Foreign Investors Return to Vietnam’s Stock Market
The VN-Index surged by 46.7 points, marking its strongest daily gain in over six months, driven by a significant improvement in liquidity and a reversal in foreign investor sentiment. After 20 consecutive sessions of net selling, foreign investors returned to net buying, providing a boost to Korean-linked stocks and the broader market.
Korean Tech and Finance Delegates to Attend Open Innovation Day
Approximately 50 investment promotion delegations from the United States and South Korea are scheduled to visit Ho Chi Minh City in six days for Open Innovation Day 2026. The event will feature 15 discussion sessions and networking opportunities, aiming to connect Korean tech firms and investment funds with local Vietnamese partners.

Deals, expansion & investment
Vietnam: The primary activity this week centers on Vietnam, where Korean component suppliers are expanding physical infrastructure in Phu Tho and Hung Yen provinces. These investments are part of a broader strategy to localize supply chains for electronics and automotive parts. Additionally, the "K-Vietnam Wellness Festa & Expo in DaLat 2026" was announced on October 21, organized by Da Hae International and local authorities, aiming to boost cultural and commercial ties in the tourism and wellness sectors.

Indonesia: No specific new investment announcements from Korean companies in Indonesia were verified for the past 24 hours. Recent major developments regarding Indonesian nickel and battery supply chains occurred earlier in the year and are outside the current reporting window.
Regulation & market context
Market Sentiment: The return of foreign capital to Vietnam’s stock market is a critical indicator for Korean investors, many of whom have been accumulating Vietnamese assets despite recent volatility. The VN-Index's rally suggests that macroeconomic stability and corporate earnings in Vietnam are beginning to outweigh global headwinds.
Global Fintech Context: While not specific to Korean companies in Southeast Asia, the broader fintech landscape in the region is consolidating. Four firms captured 86% of Southeast Asian fintech funding in the first nine months of 2026, indicating a more selective investment environment that may impact future Korean fintech expansion strategies in the region.
