US blocks more Chinese tech firms on national security concerns

Trade tensions between the world's top two economies have spilled over into the tech sector, with Trump's administration moving to essentially ban Chinese tech firm Huawei from the huge US market on security grounds [AFP]

The US Commerce Department blacklisted five Chinese tech entities Friday in a new move against Beijing's supercomputing industry likely to raise tensions ahead of a meeting between President Trump and Xi Jinping next week.

The notice targets Sugon -- a prominent Chinese supercomputer manufacturer -- along with three of its microchip subsidiaries and a computing institute owned by the People's Liberation Army.
