After a successful season with the U20s last year Channing has been training amongst the first team this term and London Broncos Head of Youth Performance Phil Jones has paid tribute to the progress he has made since switching codes aged 18.
"Mike deserves this opportunity to be part of the Wales squad; he has achieved alot in a short space of time since converting to Rugby League as an 18 year old.
"It is a credit to the hardwork he has put into both playing for the academy teams and training with the 1st grade. He has already represented Wales as an U18 scoring against Australia and I am sure he is looking foward to trying to force his way into the full squad"
The squad also contains four players from the new North Wales Crusaders club - Owain Brown, Iwan Brown and Kriss Wilkes, who are three of nine uncapped players in Iestyn Harris' squad - along with Four Nations stalwart Christiaan Roets.
Wales' youngest ever international player Rhodri Lloyd, now at Wigan, will get a chance to win a second cap while his former Crusaders team-mates, Ollie Olds and Jack Pring, both now at Leeds Rhinos, will also get a chance to shine. All of these players have impressed in the Super League under 20s competition this season.
Rhys Pugsley, who is in the Wigan Warriors under 18 side and has also been training with South Wales Scorpions, is another up and coming player who is a welcome inclusion to the train-on squad.
The squad also includes a wealth of experience. Sixteen of the 28 players are affiliated with Super League clubs while 11 of the squad featured in last year's Four Nations tournament.
Wales are unable to call on their six Australian-based players on this occasion but they will all be in contention for the matches against England and France at the end of the year.
"I'm really happy with the make-up of the squad which contains a good selection of youth and experience," said Wales coach Iestyn Harris. "It's pleasing that 19 out of the 28 players named have come through the WRL development ranks and that's down to the good structure we have in place with the right people working hard.
"It's also good that we have players in the squad from both South Wales Scorpions and North Wales Crusaders. I'm sure that they will all work hard to try and get a place in the matchday squad and I know that the Crusaders players will want to shine on their home ground.
"The French game will be a big test for us and it will be a good indication to see how our players have developed following last year's Four Nations campaign. France will also be looking to impress as it will be their first game under a new coach so we can expect a full-blooded encounter in Wrexham on Saturday 16th June."
