Jamaica is the biggest movers in the world rankings released by the Rugby League International Federation on Friday, moving from 27th to 16th.
The Jamaicans jump in the rankings are a result of their recent spate of games against Canada (14th) and the USA (10th) plus their successful first-time matches in Europe against Ireland and Wales, who were ranked sixth and eighth respectively.
"We can justifiably be a top 10 nation with the cadre of UK and domestic based players we have," JRLA director of rugby Romeo Monteith told RLIF.com.
"Our incredible performances against Wales and Ireland leaves no doubt in my mind that our strategy now to play games in Europe annually, alongside matches in the Americas Championship, is the way forward.
"Rugby league needs excitement outside the top nations, and with our unique Caribbean flair we stand ready to rock the world with reggae rugby league."
