July 5 (Asia Today) -- Samsung Electronics and SK hynix are facing a strategic balancing act as they move ahead with major U.S. semiconductor projects while preparing to invest about 800 trillion won, or $523.7 billion, in a new chip cluster in South Korea.

The two companies announced plans last week to build a semiconductor cluster in South Korea's southwest, part of a broader government-backed effort to strengthen the country's position in artificial intelligence chips and advanced memory.

The project is expected to include four new fabrication plants, two each from Samsung and SK hynix. But the plan comes as the companies are also watching possible pressure from the United States, where President Donald Trump has repeatedly used tariffs and investment demands as tools of industrial policy.
