There are fully functional Paypal in Mauritius, but only Mauritius Commercial Bank supports PayPal
if you have company in Mauritius and bank account in MCB (
https://www.mcb.mu/en/corporate/) everything might work completely well
MCB is a good bank, but it is rather difficult to get account︀ there are nowadays
you do not need to have account in US, if you have︁ account in MCB
PP requires bank account in the same country, but for some countries︂ bank account in US is an option too
Sorry, do not have experience with 2CO,︃ but I have seen recently here Diablo's answer, that 2CO is easier to set up︄ and it is possible to receive PP through 2CO
also, it is possible to set︅ up HK company + HK EMI + PP
or HK company + HK bank account︆ + PP (but this option is expensive, requires visit to HK and the UBO might︇ have business experience as a background)
