What are differences between defacto and dejure recognition of state?

De jure recognition is the formal act of one state recognising another via a statement most often voted on by the assembly or congres, while a de facto recognition is a recognition of one state of another via conduct such as opening an embassy, the head of satate of the first country visiting the country being recognised (official delegation), making formal contracts and agreements but not through drafting a resolution in which the recognition is announced. It is best for students.
