Wales coach John Kear says qualifying for the 2017 Rugby League World Cup is crucial for the game's development in the country.
The reigning European champions host Serbia in Llanelli on Saturday and face Italy away on Saturday, 29 October.
The group winners will reach the finals while the runners-up will play against the second-placed side in the group containing Ireland, Spain and Russia.
"The games against Serbia and Italy are absolutely vital," Kear said.
"We are doing many things correctly domestically and I think that's got to be reflected by the fact we're going to be at the World Cup."
Under former coach Iestyn Harris, Wales failed to reach the World Cup quarter-finals in 2013 after they were defeated by Italy, the United States and the Cook Islands.
Kear will be without Warrington Wolves' Rhys Evans and Ben Flower of Wigan Warriors, who are unavailable after playing in the Super League Grand Final at Old Trafford.
"They are bound to be a loss but I think if you look at any of the squads there's always the odd player who's missing after a long season," Kear added.
"I'm just really pleased with the squad we've got for this campaign because I feel it's got a mixture of youth, experience and quality within there."
