FASTFACT Marcos Jr. will also fly to the US to speak at the UN General Assembly on Sept. 20, Department of Foreign Affairs spokesperson Teresita Daza said in an online news conference. Manalo has said that Marcos Jr. intends to raise the case of Mary Jane Veloso, a Filipino housemaid on death row in Indonesia on drug trafficking charges. Arrested in 2010, Veloso has claimed innocence, saying she was duped into carrying a suitcase containing 2.6 kilograms (5.7 pounds) of heroin.

His talks in both countries will include regional issues such as long-unresolved territorial disputes in the South China Sea involving the Philippines, China and four other claimants, and the turmoil in Myanmar, Philippine diplomats said. The Association of Southeast Asian Nations, which includes the Philippines, Indonesia and Singapore, has been under international pressure to do more to end violence and free political prisoners in Myanmar, which also belongs to the 10-nation bloc.
