USA revokes special permissions for Samsung, SK Hynix, making it harder for them to import tech to China.

The US government has revoked special permissions that allowed Samsung and SK Hynix to import US-made chipmaking equipment to their factories in China without licenses. This move requires these South Korean tech giants to now seek individual licenses for such imports, complicating their production in China and potentially affecting the global semiconductor supply chain. The decision aims to curb China's access to advanced technology and restrict its semiconductor industry's growth.
