What is the difference between corruption and bribery?

Bribery is talking just the offence made by the side who offers some advantages (in money or any other form) to the other side in order to gain benefits which should not be given to him.

Corruption is more general and can refer to both the offence of giving and also receiving advantages in order to gain/provide benefits which should not be given to the one offering the advantages.

i guess corruption is more general and broader. it represents a depraved behaviour.
and bribery is more specific on 賄賂.
