Samsung Electronics Chairman Jay Y. Lee and SK Group Chairman Tae-won Chey are traveling to New York at the end of September 2026 to meet Nvidia CEO Jensen Huang again as Washington presses South Korean companies to expand US investment. The planned trip is drawing market attention because Samsung Electronics and SK Hynix are already pursuing large-scale spending in the US and could discuss further business ties on the sidelines of the event.

Fusion energy, often referred to as an artificial sun, has become a central focus of global sustainable energy development in recent years. However, despite nearly 70 years of worldwide R&D, commercial fusion power remains unrealized. This is primarily due to several critical technical hurdles, including heating plasma to over 100 million°C and maintaining stable long-term operation, developing materials resistant to high-energy neutrons, tritium breeding, and ensuring overall system reliability. These challenges underscore that fusion power relies not on a single breakthrough, but on a highly integrated system engineering effort.

System integration remains a key hurdle as the AI chip industry pushes for higher power efficiency and faster transmission speeds, drawing intense attention to when short-reach optical communications between racks and chips will enter practical use. Industry players say the maturity of system integration is still the main consideration for commercialization.
