Taiwan and South Korea Unite to Power AI Revolution

The devices we use every day, from iPhones to ChatGPT, depend on an unexpected friendship between two former enemies. Taiwan and South Korea, who spent decades battling each other for tech dominance, are now joining forces to power the AI revolution.

For years, these two economic powerhouses competed fiercely in televisions, smartphones, and computer chips. But the explosion of artificial intelligence changed everything, turning bitter rivals into partners who need each other to succeed.

At the center of this alliance are AI accelerators, specialized chips that can perform trillions of calculations at once. Global demand has grown so massive that no single country can meet it alone.

"We do not have time for this old-fashioned conflict," says Sung Soo Eric Kim. "Demand is so great that we have to cooperate and, above all, ensure supply."

Here's how they work together: Taiwan's TSMC builds the computing chips, while South Korea's SK Hynix and Samsung create the memory. Taiwanese manufacturers then combine everything into powerful AI servers.

The partnership centers on High Bandwidth Memory, or HBM, which AI chips need to process massive amounts of data quickly. Together, SK Hynix and Samsung produce 80% of the world's HBM, which gets paired with TSMC's processors in Taiwan.

Nvidia CEO Jensen Huang highlighted the urgency last June at a tech conference in Taipei. He autographed an SK Hynix memory chip with the words "Please make more."

The Ripple Effect

This collaboration is transforming both economies in remarkable ways. Taiwan's AI-related exports helped its economy grow 8.7% in 2025, the best performance in 15 years.

Projections for 2026 show even more impressive growth at 11.05%, which would be Taiwan's fastest pace in 39 years. The island nation even surpassed South Korea in per-person income for the first time in over two decades.

South Korea is thriving too, recording its highest trade surplus ever with Taiwan. "Taiwan has become Korea's corridor to the United States," explains tech analyst Colley Hwang.

Hwang describes the relationship as "frenemies," combining friendship with rivalry. The two nations still compete for investment and market share, but in AI hardware, they're discovering that working together creates more opportunity than going it alone.

The shift shows how shared challenges can transform relationships. What started as fierce competition evolved into recognition that collaboration serves everyone better.

Their combined expertise in chips, memory, and manufacturing has created an unbeatable foundation for AI development. Neither could dominate this space alone, but together they're shaping the technology that will define the next decade.

This partnership proves that even long-standing competitors can find common ground when the opportunity is big enough and the stakes matter to the world.
