China Rotates Fresh Troops into Hong Kong Amid Political Turmoil VOA News China has deployed a fresh contingent of troops into its military base in Hong Kong amid the territory's worst political crisis since returning to Chinese rule in 1997. State-run Xinhua news agency described Thursday's deployment as a routine rotation of personnel and equipment into the People Liberation Army's garrison in the financial hub. State television aired footage of armored personnel carriers and trucks entering the garrison after crossing the border from the neighboring city of Shenzhen. Hong Kong has been gripped by nearly three months of heated and often violent protests that began as demonstrations against a controversial extradition bill, but have since evolved into calls for greater democracy and an independent probe into allegations of police brutality. .
