closed-loop management system

BEIJING: The closed-loop management system that China will employ at the Winter Games to guard against the coronavirus will be flexible enough and ensure complete safety, Zhao Weidong, director of the propaganda department of the Beijing Olympics Organizing Committee, said on Friday.

"A closed-loop system doesn’t mean you’ll be sitting in one place all the time," he said at a news conference. "Thanks to special transportation and communication equipment, it covers many Olympics facilities."
