Is there any country that doesn't allow free currency and gold trading?

I don't really understand the question. Gold trading is mostly not controlled by the central bank, but foreign currency. Most of the countries have capital control. That means individual can buy and sell foreign currency with some limited amount.And The transaction has to be reported to the central bank. An individual can carry only a limited amount of cash out of the country. For example all countries in ASEAN have capital control,except Singapore
