If a player announced his retirement from international sports, Can he get back his retirement and play?
Who will decide on that(either the player or the country's sports authorities)?

In short Yes.
There are many examples of retired players who made a "comeback".
When a player decides to retire it is his or her personal decision, they can do whatever they decide to do.
I don't know anything about Cricket so I will refer to your question in general:
In case the player decides to do a "comeback" we can divide the "comeback" to 2 categories:
Personal sports (Like Tennis) - The player can register to play in the tournament like any other "unretired" player, e.g. Kim Clijsters who announced her retirement from professional tennis on 2007 and made a comeback on 2009 and even returned to 1st place in the WTA rankings.
Team sports (Like Basketball) - The player can announce a "comeback" and will need to find a team that will want him, or that his international team will called him up to play like every other Free Player. The best example is Michael Jordan who retired 3 times! 2 from Basketball and 1 from Baseball.
You can read about other athletes who made a comeback at the following discussion.
Referring to your focusing on Cricket and international performance I found this player: Brad Hogg as an example to a player who retire from international cricket on 27 February 2008 and made his comeback 2 years later On 1 February 2012 representing Australia at the Sydney Olympic Stadium in a Twenty20 international against India.
Yes in most professional sports a player can come out of retirement. They would need picked up by a team and signed to a contract. But there are many examples of players coming back Michael Jordan did it twice.
