I doubt it that you can block traffic from any country. I may be wrong, but, you will have to contact the hosting company that hosts your website. They can answer that better than anybody here on this Q & A forum! Good luck.

Before visiting your site visitors have to registration. In registration from there is to select option for country. But the country would be default country where he browse from country.
