Its a real pity that the most populated region in the world can't produce decent athletes of international level. Atleast now our prime minister (who understands sports is a tool of soft power) and sports minister are focused on sports. We have had many movements like Khelo India, FitIndia, Baby leagues for football etc to promote sports and unearth new talent. India has hosted many international events and looking to bid for 2026 Youth Olympic Games. I am optimistic of India hosting the Olympics in my lifetime
Pakistan has barely any funds for any sports federations and could hardly send any athletes for World Championships for wrestling, boxing, athletics, etc. Bangladesh is somewhat slowly progressing and in 2016 for first time could qualify an athlete which otherwise they receive Tripartite inviations.
Sri Lanka has few participations in athletics and weightlifting, is a force in rugby in Asia. Nepal, Bhutan, Maldives are too small states and have seen little progress
