All inbound passengers to China must report their health condition honestly before entering China, and those who conceal or falsify the report and their travel experiences will face legal liabilities, an official with the country's General Administration of Customs said.

Passengers may use a WeChat mini program or a mobile phone application developed for their convenience to complete the health condition report, which will produce a two-dimensional code, said Song Yueqian, deputy head of supervision of health quarantine.

Passengers have to present the codes to pass through customs, he added.

Apart from the health report, all passengers will be subject to temperature checkup and medical examination and screening by inspectors, he said.

Once confirmed and suspected infections and people with symptoms are found, they, and their close contacts, will be transferred to local authorities in accordance with the local joint prevention and control mechanism, he said.

Customs also has strengthened risk control on inbound vehicles. No vehicles from key countries for epidemic control will be exempted from epidemic control measures and customs officers will board all such vehicles for quarantine inspections, he said.

"All inbound vehicles will be disinfected in a strict manner to cut off transmission of the epidemic," he said.
