AMSTERDAM, Sept 6 (Reuters) - The Dutch government on

Friday said it would begin requiring export licences for two

more of ASML's "Deep Ultraviolet" or DUV lithography tools, used

in making computer chips, in the name of national security.

The United States had previously claimed the right to

regulate those tools as part of its campaign to restrict access

to advanced technology by Chinese chipmakers, to slow their

technological and military advances.

ASML said in a statement that it did not expect the change

in oversight to impact earnings this year or in the future.
