The latest curbs on exports by sector heavyweight ASML come as the United States also unveiled further measures to prevent diversion of the technology by China.

"The Netherlands will adjust the national export control measure for advanced semiconductor production equipment as of 1 April 2025," said the Dutch Foreign Ministry.

"As of that date, a national export permit will apply to more types of technology," it added in a statement.

Dutch Foreign Trade Minister Reinette Klever said the new steps were aimed specifically at curbing the export of specific measuring and inspection equipment used in semiconductor production.

"We see more safety risks with the uncontrolled export of this equipment," said Klever, adding "That's why an export licence is now required."

But the extension of the measures "is aimed at a very limited number of technologies," the Dutch Foreign Ministry said.

"The Netherlands plays a unique role in this. It is important that we do not unnecessarily disrupt the chip industry," Klever added.

"When expanding the export control measure, we have therefore proceeded as precisely as possible," she said.

ASML in a statement to AFP said it saw "no additional impact" to what was reported by the company in early December, when it brushed off the announcement of fresh US export curbs to China and kept its forecasts unchanged for 2025.

Investors also seemed unmoved, with ASML's share price remaining flat on the Amsterdam stock exchange's blue chip AEX index.

Beijing however said it has "noted the announcement... and has expressed high concern to the Netherlands about this."

The Chinese Commerce Ministry in a statement called on the Netherlands to "respect market principles and the spirit of contract... and maintain the stability of the global semiconductor industry and supply chain."
