Foreign nationals employed in China under standard labour contracts are typically required by law to contribute to China's mandatory social insurance system, which includes a basic medical insurance component. This mandatory contribution — paid by both the employer and employee — provides access to the public hospital network for outpatient and inpatient care, subject to co-payments and reimbursement caps.
Many large Chinese commercial insurers (including PICC Health, Ping An Health, China Life, and others sometimes grouped under informal 'ABC' shorthand references to non-name-brand local providers) offer supplemental health insurance products designed to bridge the gap between mandatory social insurance coverage and the more comprehensive care expatriates typically require.
These supplemental products are denominated in CNY, sold by mainland-licensed entities, and designed to work in conjunction with social insurance rather than replace it. Common benefits include higher reimbursement limits for hospitalisation, access to semi-private ward accommodation, outpatient specialist consultation cover, and pharmaceutical supplements. Some products include a limited international emergency evacuation benefit.
The advantages of supplemental local cover are primarily cost and administrative simplicity: premiums are paid in CNY from a Chinese account, the insurer is locally regulated (meaning disputes can be escalated to Chinese regulatory channels), and the hospital network is the full public hospital system plus some private clinics.
The limitation is that these products rarely provide the international evacuation, worldwide cover, or home-country treatment access offered by offshore international plans. Many expatriates maintain both — the mandatory social insurance, a local supplement, and an offshore international plan — accepting some premium overlap in exchange for comprehensive coverage.
