IMHO, it's impossible to conduct their own researches for all drugs within their own countries.
Instead, most countries simply follow US FDA.

You can conduct your trial anywhere, and submit the result to multiple countries, including FDA. It is true that other countries views FDA approval as valuable piece of info when making their own decision. It is an endorsement to some degree.
