Cambodia passport with new name, takes about 10 to 30 days, only need a clean criminal record (or relatively clean it is something that can be talked about) but costs 300k. No advance payment required, escrow.
Cambodia is non CRS and dosen't tax personal income that is not from Cambodian, work nor foreign pensions, nor foreign sourced income and you can easily open USD bank accounts with high interest rates. Also it's a nice, safe, tropical country with low cost of living and a booming economy.
Chinese people use this route very often.
