BEIJING, June 21 (Reuters) - China imposed

countermeasures on Lockheed Martin's ( LMT ) relevant entities and

senior executives on Friday over the United States' arms sales

to Taiwan, a foreign ministry statement showed.

China will freeze movable, immovable and other kinds of

property of Lockheed Martin's ( LMT ) senior executives including its

chairman James Donald Taiclet, and will bar them from entering

the country.

China has applied sanctions on U.S. companies including

Lockheed before for selling arms to democratically governed

Taiwan, which Beijing claims as part of its territory.
