Taiwan's opposition is warning that US weapons sales to the island could become a bargaining chip in upcoming Trump-Xi talks — a serious risk for Taiwan's defense if true.

• Foreign reports say Xi Jinping plans to push Washington to stop selling arms to Taiwan, and that the issue may land on the US-China negotiating table.
• The KMT says trading away arms sales would break Reagan's 1982 "Six Assurances," which promised the US would not consult Beijing beforehand.
• The party wants President Lai Ching-te to call a top-level national security meeting instead of insisting Taiwan-US talks are going fine.
• KMT lawmakers argue Trump is willing to sell Taiwan what it needs, so Taipei should state its position publicly and push its "Taiwan Shield" plan, including drones.
• The argument: Washington and Taipei cannot control China together, but they can keep the Taiwan Strait calm together, which serves both sides.

Outlook: Pressure on Lai's government to spell out its red lines will grow as the Trump-Xi meeting approaches.
