PNOC has held SC57 for over a decade, unable to exploit for two reasons:
1. It does not have the industrial capability to do so, and would have to farm out the work,
in which case the subcon might demand to buy-into a share of the operation or, IOW, turn
it all into a joint venture (JV). Think of how SPEX, Occidental Pet., etc. protect their assets.
2. China would throw a hissy fit over what they claim as their natural resources.
PNOC addressed the above two issues by "farming out" the heavy lifting to CNOOC, which
provided China with financial/mineral incentive to play along, but (expectedly) CNOOC
demanded to buy-into a share of the operation: hence the statement that CNOOC was
"farmed in". Ditto with Mitra.
We have to remember that this arrangement dates back to 2005, when PNOC/CNOOC/Mitra
started surveying SC57, which arrangement did NOT prevent China's aggressively asserting
its false claims of sovereignty over SC57 and much of the rest of WPS from 2006 to present.
Where recognition of Philippine sovereignty over SC57 is concerned, China is aloof
behind a triple blind:
1. CNOOC is a state-owned business, NOT a state agency
2. CNOOC is arguably only SC57 (sub)operator-in-fact, under PNOC's operation-by-law, kasi...
3. CNOOC has yet to actually formalize its buy-in, if the Deeds of Assignment aren't inked.
The fact that the Deeds of Assignment were in limbo for so long was good for China, and
evidence that China controls (and has controlled for some time) higher offices/officials in PH,
because such a limbo would allow CNOOC (and therefore China) to profit, without being
fully-answerable (as JV stakeholder) to Philippine sovereignty.
I wouldn't be surprised if the JV is also registered in China, with PNOC as farmed-in consult,
(with Mitra again included), to respect Chinese sovereignty over SC57, but said registration
is being kept hush-hush especially here in the Philippines.
You can look at it as China laughing at Filipinos for being so easy to play for fools...
but you also have to realize that ANY industrial partner, foreign or local, would play just as
hard to protect its interests vs those of PH.gov, and also realize that, ultimately:
1. PH.gov stands to reap substantial returns from such arrangements (see Malampaya/SPEX)
2. PH.gov couldn't reap said returns without resorting such arrangements.
