Sept 8 (Reuters) - The United States is proposing annual

approvals for exports of chipmaking supplies to Samsung

Electronics ( SSNLF ) and SK Hynix's ( HXSCF ) China-based

factories, Bloomberg News reported on Monday.

Officials in the U.S. Commerce Department last week

presented to Korean counterparts a "site license" idea to

supplant indefinite authorizations the chipmakers secured under

the previous administration, the report said, citing

unidentified sources.

Reuters could not immediately verify the report.
