A sanction is a punishment or penalty that's enforced when someone breaks the rules or doesn't follow what's agreed upon.
Think of it like this: imagine you're part of a team and everyone agrees to work on a project together. But one person decides not to do their part, and as a result, the whole project gets delayed. To make sure people stick to their promises, there might be consequences - let's call them sanctions - for those who don't cooperate. For instance, maybe that person has to apologize publicly or help with extra tasks on top of their original responsibilities. The idea is to encourage everyone to do their part so the team can achieve its goals.
An approval, by an authority, generally one that makes something valid.
Example: The whalers had been operating in the contested waters off the island with sanction from the Japanese government.
To ratify; to make valid.
