You need to take a class in connecting dots, DL.
The dots you're connecting are the fly specs on your computer screen. I worked in international trade and finance. The corporation structures that the Republicans are telling you are "shell corporations for laundering money", are in fact standard for anyone doing business in a foreign country.
Furthermore, you need a different corporation, for each country you're investing in, so 20 shell corporations among 9 people investing and/or working in 3 countries, is actually a low number.
I acted as a corporate clerk for the largest residential development corporation in North America. They had 200 active corporations at any given time, and incorporated a new LLC every time they made an offer on a property. If the offer fell through, the LLC was never used again. If the offer was accepted, the LLC was added to the active list, and used to complete the purchase and development of the property. When the project was completed and sold, the LLC was wound up and dissolved.
No money laundering involved. This simply protected all of the rest of their projects from being taken down by the failure of one of their projects. Money isn't being laundered by the Biden's LLC's. Investments are being walled off, from the rest of the portfolio, for protection.
Investments in China are particularly vulnerable. While China claims to allow capitalism, they will just swoop in and take over a company. A friend spent 10 years building a school for autisic children in Beijing, and the government gave her 6 months to sell out or they'd take revoke her charter. I'm not real clear on exactly what happened, but she did find a buyer and left China.
My impression from the Hunter Biden got $10 million out of China story is that something similar was happening with his Chinese investments. He'd pulled all of his family into this investment in the Chinese energy market, and now the Chinese government was pushing them all out.
But I have yet to see anything that would lead me to believe that Joe Biden was involved in any of it, or that Hunter Biden was doing anything illegal, in terms of business. Lawyers know where all the lines are, and which ones can be crossed and which ones can't.
