Cambodia won their first ever regional tournament with last year's two-match series versus Brunei in Phnom Penh.
2014 brings new challenges and a new challenger as the Division welcomes back Mongolia for the first time since 2010. Cambodia will now test its mettle on the road with Brunei hosting the Asian 5 Nations for the first time ever in 2014.
Returning for another tilt at its first ever Division Four title, Brunei will be keen to make the most of its first opportunity to play A5N rugby in front of its home audiences.
After being swept last year by Cambodia in Phnom Penh, Brunei will be intent on coming good at home but will also contest with the unknown quantity represented by Mongolia as they make their Division IV debut.
The Asian Rugby Football Union is excited to welcome the return of Mongolia to A5N play in 2014.
Mongolia have been missing from the 15s scene for the past few years but are keen to make their mark on their return.
Their more fancied opponents in Cambodia and Brunei will do well to be wary of the Mongolians who have proved gritty opponents at regional level.
