/ˌriˈɛntər/ – Verb
Definition: tái nhập, quay lại
A more thorough explanation: to continue with discussions or negotiations after having stopped; to reengage; to start again; to recommence. The term is often used when it had seemed that negotiations had permanently broken down, but then start again following a change of position of one or more of the parties.
Example: Trump has praised a North Korean statement expressing willingness to reenter talks.
