Hong Kong implemented their current health warnings policy starting October 2007. Cigarette packages are required to have a health warning cover 50% of the front and back of the package, in both Chinese and English. Overall, 50% of the package space is appropriated to health warnings. In total, a set of 6 health warnings are rotated on cigarette packages each year, with each warning being shown in equal proportion over that period.
