South Korean President Lee Jae Myung completed an 11-day [1] diplomatic tour of the United States and South America in July 2026.

The trip represents a strategic effort to solidify South Korea's position as a global AI chip hub while diversifying the supply chains for essential minerals and energy. By strengthening ties with both North and South American partners, Lee aims to insulate the nation's tech industry from geopolitical volatility.

During the visit to San Francisco, the president focused on securing U.S. investment in AI and semiconductors [2]. These discussions were central to a broader vision of establishing South Korea as a primary center for artificial intelligence hardware development [2].

The diplomatic itinerary extended to three South American countries: Brazil, Chile, and Argentina [3]. In these nations, the administration pursued agreements for critical-mineral cooperation, and energy security [2, 3]. These minerals are essential for the production of high-tech components and green energy infrastructure.

While some reports suggested a visit to Germany, other accounts focused exclusively on the Americas [4, 3]. The primary objective remained the expansion of economic and strategic partnerships to ensure a steady flow of resources required for advanced manufacturing [2].

President Lee's tour focused on three key areas: AI semiconductor deals, critical-mineral cooperation, and energy security [2]. The 11-day [1] journey concluded around July 22, 2026 [3].

This diplomatic push signals South Korea's intent to reduce reliance on single-source suppliers for critical minerals, particularly as the global race for AI supremacy intensifies. By pairing high-level tech deals in the U.S. with resource agreements in South America, Lee is attempting to build a vertically integrated strategic network that secures both the intellectual property and the raw materials necessary for the next generation of semiconductors.
