They are two of eight official tournaments of the Asian Pacific Golf Confederation (APGC).
The first will be from October 15-18 while the second one will be from October 30 to November 1 at the Vinpearl Golf Hai Phong golf course.
Each event will feature more a hundred athletes from APGC's 47 members, including Australia, Japan and China, Hong Kong, Thailand and the hosts, said the VGA.
The biennial Nomura Cup, for men's teams, is held over four days with 18 holes of stroke play. Results from the two players with the best score will be counted as the team's result in each round. The team with the best gross over 72 holes will lift the championship trophy.
Australia has previously dominated, winning the cup ten times, followed by Japan with seven. Meanwhile, the Asia-Pacific Senior Amateur Championship is the premier team and individual event for senior golfers across the region.
The tournament provides a chance for players aged 55 and above to compete for the ultimate prize – an exemption into the R&A Senior Amateur Championship. Since its inception in 2006, it has become a pinnacle event for senior amateur golfers.
The men's competition will feature a team format where the top three of four scores from each round will contribute to the overall team score across the 54-hole event.
In the women's competition, the best two of three scores each day will count toward the team total. Women’s competitors must meet the age qualification of 50 years and older.
Last year, Australian James Lavender and Sue Wooster took the individual titles and Australia also secured teams' cups at the Vinpearl Golf Nam Hoi An in Quang Nam province.
