The National Immigration Administration announced the measure on Monday, and it took effect immediately.

The policy applies to groups of two people and more from ASEAN member states, including Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam, the South China Morning Post reported.

To qualify, travelers must book through a Chinese travel agency. The tour group members must also enter and leave China together.
