How is Marcos Jr. Pro-China though? I understand and have read some of his past statements with regards to China along with his most recent visit to the country, but in terms of actual actionable policies, he's been nothing but pro or even neutral. He has exacerbated the tension in the SCS and in my view needlessly escalated an issue that should have been handled diplomatically and most importantly not be used by America for their own desired geopolitical interests in the region.
As for Marcos Jr. being under the influence of his wife, he's simply following the old familiar tradition of his late father. Imelda was seen as the corrosive influence to Marcos Sr. which ultimately undone he's supposed virtues and good intentions for the Philippines. Besides, I keep hearing amongst Filipinos that Marcos being of "ILOCANO" him being under the thumb of his wife is par for the course as many ILOCANO men suffer the same fate. You must recognize that the Philippine people comes from differing cultural values, norms, and mores. Not to mention ethnic languages that comes with its own sub-culture of which ILOCANO is one of the more prominent in the Philippines, the other is Visaya/Cebuano which is spoken in the Southern part of the Philippines like Cebu to Mindanao where DUTERTE is from.
