A Romney administration may consider providing more advanced weapons to Taiwan to maintain strong US military capabilities in the Asia-Pacific region, a senior foreign policy adviser to the Republican presidential candidate said on Tuesday.

"When President Obama refused to sell F-16C/D (jet fighters) to Taiwan, Governor Romney was very clear to state that he disagrees with that decision," Richard Williamson said at a foreign policy panel hosted by the International Republican Institute on the sidelines of the Republican National Convention.

The 63-year-old Williamson has served on foreign affairs for three Republican presidents. Currently, he is a partner at a Chicago-based law firm.
