In 1987, due to the fact that there were too many reporters entering Tibet and bringing news out with them, the PRC Ministry of Foreign Affairs enacted a "ten-day rule," which required reporters stationed in Beijing to inform the Ministry of Foreign Affairs ten days in advance before leaving the capital. Most remote areas still remain off-limits to foreigners.
一九八七年，因為有太多記者進入西藏，將消息帶出來，中共外交部因此製定一項「十天規定」：要求駐北京記者如果要離開北京，必須在十天前告知外交部；而大部分的偏遠地區，經常都不讓外國人進入。
