what is the difference between nationalization and privitisation?

privitisation应该是privatisation吧 意思是 私有化，非国有化
nationalization 意思是国际化
国际化和私有化之间的区别是什么

Nationalization is the act of taking an industry or assets into the public ownership of a national government. Nationalization usually refers to private assets, but may also mean assets owned by lower levels of government, such as municipalities. The opposite of nationalization is usually privatization or de-nationalisation, but may also be municipalization.

Privatization is the incidence or process of transferring ownership of business from the public sector (government) to the private sector (business). In a broader sense, privatization refers to transfer of any government function to the private sector including governmental functions like revenue collection and law enforcement.
