There is no fixed CPM per country. Rates are fully dynamic: they differ from site to site and change over time. Two websites with the same amount of traffic from the same country can earn very differently.
What affects your CPM:
The country and device of your visitors (mobile traffic and Tier-1 GEOs are usually in higher demand);
The ad format (Onclick, Push, In-Page Push, Vignette, and Direct Link are priced differently, so compare them separately);
Your website type and how engaged the audience is (how often users click, register, or buy on advertisers' pages);
Traffic sources and quality (bot, proxy, or incentivised traffic brings the CPM down);
Ad placement and frequency;
Seasonality (rates usually dip in summer and grow in Q4);
The share of visitors using ad blockers.
