From Reuters, via ABC News:
Shouting “Japanese invaders must die”, thousands protested against Japan’s wartime past in eastern China today, hurling rocks and bottles and burning Japanese flags at Tokyo’s consulate in Shanghai.
But with thousands of paramilitary police on the streets of Beijing and students warned against protests, authorities headed off a repeat of last weekend’s violent demonstrations in the capital, which hosts Japan’s Foreign Minister on Sunday.
Police also barred incidents in southern Guangzhou and south-western Chongqing, where thousands marched last weekend.
