To answer your question, I ask you to please go to the very first page of part 2, page 4, from the Bureau of Immigration of the Philippines. Paragraph 2 very clearly says the following:
The consistent policy of the Philippine Government is to repatriate said RVNs (the returning Vietnamese) to Vietnam, or resettle them to a third country willing to accept them. The Philippines has never been, and is not, a resettlement country. It also has no intention of socially integrating persons whose applications for asylum/refugee status it denied in the first place.
They've always maintained that. And the following letters, signed in 2003-04 from the House of Representatives and the Philippines Senate, confirmed that they have no durable solution for these people.
