The so-called foreign exchange documentary usually has two forms, one is automatic documentary and the other is manual documentary. Either way, there is no actual guarantee, and the risk is high, and the risk is entirely borne by the choice of documentary;

As for the management of foreign exchange assets, due to the restrictions of national policies, compliance investment companies, fund companies and asset management companies supervised by the regulatory authorities cannot package them into asset management products, and usually they can only dock the capital side in the form of trading agent.

I hope this answer is helpful to you.
