The agreement would extend some export controls the US adopted in October to companies based in the two allied nations, including ASML Holding NV, Nikon Corp and Tokyo Electron Ltd, the report said.

Officials from the Netherlands and Japan were in Washington discussing a wide range of issues in talks led by White House national security adviser Jake Sullivan.

John Kirby, the White House national security spokesman, earlier said the officials were talking about issues that are “important to all three of us.”

“And certainly the safety and security of emerging technologies is going to be on that agenda,” he told reporters.

A source familiar with the talks said restricting exports of semiconductor manufacturing equipment to China was among the topics.

Getting the Netherlands and Japan to impose tighter export controls on China would be a major diplomatic win for President Joe Biden’s administration, which in October announced sweeping restrictions on Beijing’s access to US chipmaking technology to slow its technological and military advances.

When asked about the Bloomberg report, the White House declined to comment beyond Kirby’s earlier remarks.

The Dutch foreign ministry and a spokesman at Japan’s economy, trade and industry ministry declined to comment.

A spokesman at Nikon declined to comment, saying the company could not speak about something that had not been officially announced. Officials at Tokyo Electron were unavailable for comment when Reuters contacted them outside regular business hours.

The Netherlands’ prime minister, Mark Rutte, earlier said that it was not clear whether his government would disclose the result of ongoing talks with the US over new export restrictions for the semiconductor industry.
