Having led the Black Stars between 2012 and 2014, Appiah has been given a second chance to lead the team to continental glory for the first time since 1982.
And Kingston believes the 56-year-old's injection of fresh blood into the latest squad is a sign of good things to come.
“Kwesi has put together very good and hungry players who are ready to die to achieve something," Kinston said on GH One TV.
"We just need to support them to make that objective [of winning the Afcon] achievable.
“With the new players in the team, each player will play to claim a position in the team and to sustain his stay.
"That competition is one of the things needed to win trophies for the country."
Appiah's recent squad, which took on Ethiopia, Mexico and the USA, included six home-based debutants as well as some foreign-based first timers.
The last two players, however, failed to honour the invitation due to various reasons.
