Trump says the US should hit Taiwanese chips with tariffs of 50%, 100% or even 200% — bad news for Taiwan's chipmakers and anyone relying on cheap chip supply.

• Speaking at a Republican campaign event in Texas, Trump said Taiwan should pay whatever tariff rate it takes to sell chips into the US.
• He blamed past US presidents for letting the chip industry drift to Taiwan, calling the decisions foolish.
• He pointed to Intel's troubles as the result, saying Intel's CEO came to him for help.
• Tariffs, he said, have already brought in big money and record foreign investment in the US.
• The goal is to force chipmakers to build and keep more production inside the US.

Outlook: Taiwan's chip sector faces more tariff pressure as Trump keeps the issue front and center heading into the midterms.
