Is Aspartame banned in other countries?

Many synthetic dyes, chemical dough conditioners, and preservatives like Aspartame are either banned or require mandatory health warning labels in the European Union, the UK, or Japan under the precautionary principle, whereas the US FDA relies on legacy GRAS designations.
