Myanmar will be the main rival of Coach Mai Duc Chung's players in the race to top Group B.
At the SEA Games 31 semi-final, Myanmar's players demonstrated an impressive defence capacity and only gave in after the solitary goal scored by Vietnam captain Huynh Nhu.
In the meantime, Group A is expected to see more intense competition with the presence of Australia, which currently stands at number 12 on FIFA's women's rankings.
The remaining teams in Group A are Thailand, Singapore, Indonesia, Malaysia and host the Philippines.
Group matches will take place in a round-robin format to select the two best performers for the semi-finals.
The tournament is scheduled to take place from July 2-14 in the Philippines.
Vietnam is the reigning champion after defeating Thailand during extra time in the 2019 final.
The team will assemble again on May 30. Before arriving in the Philippines for the Southeast Asian championship, Chung and his players will have a training tour in France.
