Taiwan’s government has promised its most advance semiconductor technology will not be moved to the US under a new $100bn (£79bn) deal signed between the chip maker TSMC and Donald Trump, amid accusations that it is allowing the island’s national security to be undermined.

The government said the deal must still go through government assessments, which would take into account the interests of the country as well as investors.
