Taiwan's government is pressing US contacts to keep arms sales on track before Trump and Xi meet, a tense moment for Taipei's security.

• Taiwan's foreign ministry says national interest will set the tone of the Trump-Xi talks.
• Taipei and its representative office in Washington are lobbying to keep US and Taiwanese interests aligned.
• Securing pending US weapons purchases is the top priority right now.
• Taiwan's security team has war-gamed multiple scenarios and prepared responses for each.
• Leaders in eight other countries, including Australia, are watching the outcome for Taiwan Strait stability.

Outlook: No one can predict what the two leaders agree on, so Taipei will keep pushing Washington to treat Taiwan's self-defense as an American interest.
