Carrying cash from China to Thailand
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Part of this route is a hard limit, not paperwork. Leaving China, General Administration of Customs of China caps what you may carry at CNY 20,000, a prohibition, not a form. Entering Thailand, Bank of Thailand (exchange control) requires a declaration above THB 450,000. The two rules are independent: satisfying one does not satisfy the other.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving China | max CNY 20,000 | Customs declaration form | General Administration of Customs of China |
| Entering Thailand | THB 450,000 | no form | Bank of Thailand (exchange control) |
The same ¥20,000 cap applies on departure. Foreign currency above USD 5,000 is released on the strength of the declaration made on your last entry, so keep the endorsed copy, without it, customs releases only what a certificate from the Foreign Exchange Bureau or an authorised bank covers.
No limit applies to bringing baht or foreign currency into Thailand. A customs declaration is required above THB 450,000, or above USD 15,000 in foreign currency banknotes.
Currencies
China uses CNY; Thailand uses THB.
