Scared by crowds of bulk milk buyers and speculators from the Chinese mainland during the Spring Festival holiday, some retailers in Macao have reportedly imposed quotas to ensure that local milk supply is not affected.

Similar worries are spreading in Hong Kong, where some brands of milk powder went out of stock during the holiday.

We are sorry for our fellow nationals in Macao and Hong Kong whose daily milk supply was disrupted. We are sorry for the fathers and mothers on the mainland, too, who may lose a convenient source of safer and more reasonably priced milk supply for their children.
