China's top quality watchdog has ordered intensified safety checks of amusement rides ahead of the National Day holiday, which runs from Oct 1 to 7, following two accidents that killed one person and injured three this month.

The General Administration of Quality Supervision, Inspection and Quarantine has required quality supervision officials nationwide to intensify checks on rides such as swing rides, roller coasters and cableways at amusement parks and scenic spots, Li Benjun, a spokesman for the administration, said at a news conference on Sunday.

The order came after two accidents this month, including one involving a swing ride at an amusement park in Xi'an, Shaanxi province, on Sept 15 that injured three people, one severely.
