The supervision of individual purchase of foreign exchange has become stricter. The State Administration of Foreign Exchange requires individuals to sign the Application for Individual Purchase of Foreign Exchange when purchasing foreign exchange, which clearly states that "when purchasing foreign exchange, domestic individuals shall not use it for overseas capital projects such as buying houses, investing in securities, purchasing personal insurance and investing in dividend insurance." At the same time, the regulatory authorities claimed that once the behavior of "ants moving" was discovered, if the circumstances were serious, a fine of more than 30% of the amount of foreign exchange evaded could be imposed.
