About ten years ago there were some very promising developments coming from Cuba. Much of it was due to the work and enthusiasm of Phil Melling. At the time there would appear to have been little interest shown by the Rugby League authorities and sadly Phil shortly after passed away. He was someone who was well respected in his home town of Wigan and later in South Wales where he had gone to live.

It took me three minutes to find the relative Facebook and websites of the three nations mentioned...all showing fantastic local development ... also check out the 2017 Wikipedia for World Cup qualifying .. you will see all three were involved in the qualifying competition

You might want to also check out the Balkan Superleague competition run by the entrepreneurial Serbians ... which is perhaps the most exciting grass roots development currently in the game!

I'm aware of Phil Melling, he was a good guy. But not sure where you've got the info from regarding Cuba as I don't ever remember any mention of there being any type of RL presence there.
