U.S.'s Asia Allies See New Threat From Balloons Amid China Spying Row

America's allies in Asia are raising their vigilance against high-altitude balloons after Washington accused Beijing of using them in a global spying program, ending years in which unannounced incursions by balloons have largely been tolerated in the region. Balloons of undeclared origin are seen each year around the Asia-Pacific region. One military officer in Taiwan with access to daily intelligence reports said suspected Chinese balloons are spotted by Taipei roughly once every quarter, mostly over Taiwan's outlying islands near the Chinese coast.
