A Trump-Xi summit in Washington has Taiwanese officials pushing for national security preparations, a sign of how much is riding on the outcome for the region.

• Trump and Xi meet in Washington on the 24th, their second sit-down since May.
• Taichung mayor Lu Shiow-yen is urging Taiwan's government to convene a national security meeting ahead of the talks.
• Japan is already moving first, with Prime Minister Takaichi flying to the US to gauge what the summit means for Tokyo.
• Taiwan's worry is straightforward: two superpowers bargaining over trade and security could trade away things that matter to smaller neighbors.

Outlook: Expect Asian capitals to scramble to read the results as soon as the meeting ends, with Taiwan watching for any shift in US commitments.
