That said, Duterte's rhetoric on this matter has been as erratic as it has been bombastic — you can apply that to much of his policy dicta. At one point on the campaign trail, he said that he would ride a jet ski to the disputed Spratly Islands and plant the Philippine flag there.
At other times, though, he has said that if the Chinese leave his waters alone, then he can work with that.
"He could start a war with China. He's very inconsistent in what he says," one Manila resident, Joyce Asilo, told The New York Times last month.
So this is going to be a wild one, people.
A little bit about this guy

Duterte was the mayor of the Philippine city of Davao for six terms. In that time, he came to be known for his bombastic, off-the-cuff, and sometimes violent rhetoric. As a candidate, he often used that rhetoric to frame how he would rid the Philippines of violence, drugs, gangs, and corruption — that's what won him the presidency.
"Just because you're a journalist you are not exempted from assassination, if you're a son of a b----," he said at a press conference earlier this month.
When it comes to the South China Sea lately, Duterte has exhibited another Trump-like quality. He says that he's ready to talk to China if the US — the main ally to smaller countries countering China's dominance in the region, including Brunei, Vietnam, Malaysia, and Taiwan — does not support his country the way he thinks it should. From now on, all negotiations will consider the Philippines first.
"We have this pact with the West, but I want everybody to know that we will be charting a course of our own," he said, according to a Reuters report. "It will not be dependent on America. And it will be a line that is not intended to please anybody but the Filipino interest."
He later point-blank asked the US ambassador to the Philippines, Philip Goldberg, "Are you with us?"
Goldberg said that the US would back the Philippines only in the event of a Chinese attack.
That didn't seem to be the response Duterte was looking for, as he later said that he would send a representative to China to talk.
"Can you [the US] match the offer? Because if you cannot match the offer, I will accept the goodwill of China," he said, according to Reuters.
That said, China isn't in the mood for "offers" right now.
Duterte's ascension to power is happening at a delicate time in the relationship between the two countries.
The outgoing president of the Philippines filed an arbitration under the UN Convention on the Law of the Sea (UNCLOS) over China's actions in the waters. Duterte said that he would wait to see what the UN says before he decides what to do, but either way China is upset about that, to say the least.
"The three 'NOs' are: the Philippine action has no basis on international law, the international arbitration tribunal has no jurisdiction over the case, and the tribunal has no legitimacy, explained Zhou Jian, a representative for boundary and ocean affairs of the Chinese Foreign Ministry.
"China's stance on the South China Sea issue has won many countries' support. However, some nations for their own interests called China 'despising international law' or 'fearing to lose.'
"In response to such slander, Zhou said it is the Philippines that initiated the arbitration against international law."
Yes, people. Slander. Again, this should indicate that China is not in a negotiating mood.
A little about this water — and why everyone wants it
(South China Sea, y'all.US Navy)
The South China Sea will undoubtedly be the battleground of the future.
The aforementioned territorial claims from Vietnam, Malaysia, Brunei, the Philippines, Taiwan, and China make the South China Sea one of the most disputed places on the planet.
These waters have proven oil reserves of 7 billion barrels, and an estimated 900 trillion cubic feet of natural gas, according toRobert D. Kaplan, an author and the chief geopolitical analyst for Stratfor.

And if Chinese calculations are correct, then the South China Sea will ultimately yield 130 billion barrels of oil, which is second only to Saudi Arabia, making the South China Sea "the second Persian Gulf."
China, by far, has helped itself to the largest slice of cake in the South China Sea, staking out it's claim with its Nine Dash Line.
All the while, Chinese President Xi Jinping has steadily consolidated the world's largest military coupled with roughly $356 billion in military spending power.
In short, China is dominating the maritime heart of Southeast Asia.
Enter the Philippines, stage left.
The Philippines is formally arguing China's Nine Dash Line, and an international-court ruling is expected in the coming weeks.
And while the consensus among experts is that The Hague's ruling will go largely against Beijing, the South China Sea remains in a dangerous limbo.
