Countries where BTC can be bought cheaper than at crypto-exchanges

[siaeae]

In countries like China and Vietnam, where at the moment online exchanges are banned by their governments, how do their citizens sell their Bitcoins? It seems to me only peer-to-peer, no? And if this is true, wouldn't they be incentivised to sell at a cheaper rate for cash? Since this may be the only (?) way they can sell their BTCs at the moment?

Are there other countries in the WESTERN world where online exchanges are not allowed at the moment?

What are your thoughts on this, or any experience buying BTCs in China or Vietnam P2P?

Thank you!

P2P are usually more expensive, you need to consider demand is higher than offer, if it is banned it means less liquidity meaning offer even lower than normal so higher spreads. The higher the liquidity and lower spreads, more offer than you get it cheaper.
