Do China citizens who hold American green cards have to pay taxes to the United States after paying taxes on the money earned in China?

Once China investment immigrants obtain American status, their future investment and business income in China or other overseas countries will actually be taxed to the IRS. In many countries, in order to avoid double taxation, after China pays taxes according to law, the tax payment certificate provided to the United States can be deducted accordingly, but if it is insufficient, the difference will still be made up.
