MANILA/BEIJING, March 28 (Reuters) - The Philippines will implement countermeasures against "illegal, coercive, aggressive, and dangerous attacks" by China's coastguard, President Ferdinand Marcos Jr. said on Thursday, upping the stakes in an escalating row in the South China Sea.
The Philippines is furious over what it calls repeated hostilities by Chinese vessels around disputed features inside Manila's 200-mile exclusive economic zone. The United States has weighed in with moral support for its former colony and military ally.
Marcos did not specify what the countermeasures would entail, but said they would come in succeeding weeks and be proportionate, deliberate and reasonable in response to what he called open and unabating attacks.
"We seek no conflict with any nation, more so nations that purport and claim to be our friends but we will not be cowed into silence, submission, or subservience," Marcos said on Facebook.
The deterioration in relations with China comes as Marcos seeks to deepen defence ties with the United States, increasing U.S. access to Philippine military bases and expanding joint exercises to include sea and air patrols over the South China Sea, frustrating Beijing.
Chinese Defence Ministry spokesperson Wu Qian on Thursday said the Philippines was to blame for the breakdown and was counting on support from external forces while peddling misinformation and infringing on China's sovereignty.
'DANGEROUS PATH'
"It is straying further down a dangerous path. The Chinese side will not allow the Philippines to act willfully," Wu told a briefing.
"We have responded with legitimate, resolute and restrained actions. The Philippine side should realise that provocations will only do themselves more harm than good, and soliciting foreign support will lead nowhere."
The latest flare-up occurred last week, when China used water cannon to disrupt another Philippine resupply mission to the Second Thomas Shoal for soldiers posted to guard a warship intentionally grounded on a reef 25 years ago.
China, which claims almost the entire South China Sea as its own, warned the Philippines on Monday to behave cautiously and seek dialogue, saying their relations were at a "crossroads".
Marcos said he met his defence and security officials and has been in communication with "friends in the international community".
"They have offered to help us on what the Philippines requires to protect and secure our sovereignty, sovereign rights, and jurisdiction while ensuring peace and stability in the Indo-Pacific," Marcos said.
U.S. Defense Secretary Lloyd Austin on Wednesday reaffirmed Washington's commitment to a 1951 mutual defense treaty with the Philippines and criticised as "dangerous" China's actions at the Second Thomas Shoal.
In a phone call on Wednesday with Philippine counterpart Gilberto Teodoro, Austin "reaffirmed the ironclad U.S. commitment to the Philippines" which it said was undertaking a lawful resupply mission.
The Philippine-U.S. treaty binds both countries to defend each other if under attack and includes coastguard, civilian and military vessels in the South China Sea.
Asked about Marcos vowing countermeasures, China's defence spokesperson Wu said Beijing would take resolute and decisive measures to defend its sovereignty.
"China firmly opposes the Philippine side's treachery and provocation, as well as its fabrication of lies to mislead international public opinion," Wu said.
