There are new rules in Hong Kong due to the trade war between China and the USA.
Things are changing in Hong Kong as well. A new law dictates that any person entering or leaving Hong Kong must make a written declaration if in possession of the equivalent of more than HK$120,000 in cash, or about US$15,200. For those flying from Mainland China to Hong Kong, this law was announced on the plane. We saw more obvious inspections at the Hong Kong airport on a recent trip. And, Hong Kong banks are asking more and more questions about the accounts of diamond and colored gemstone businesses. Big banks are sometimes even forcing companies to close their accounts.
