KYC/AML for Frontier Markets - Practical Challenges

Been diving deeper into the nuances of EM investments, specifically looking at some of the frontier markets. It's fascinating how much growth potential there is, but it also brings up some significant compliance hurdles. I'm wondering, for those of you actively involved in funds or platforms dealing with these regions, how are you practically managing enhanced KYC/AML requirements?

Specifically, what are some of the less obvious challenges you've encountered when verifying UBOs or even just basic identity in jurisdictions with less robust public registries? Are there specific third-party solutions that are proving more effective in these areas, or is it still a heavily manual, boots-on-the-ground kind of effort? The regulatory landscape is constantly shifting, and staying ahead of potential red flags without stifling legitimate trade seems like a real balancing act. Any insights would be greatly appreciated.
