Updates in the aftermath of the sinking of a Filipino fishing boat by a suspected Chinese trawler.

A philanthropist from Shanghai has turned over a commercial fishing vessel to replace F/B Gem-Ver 1, which was damaged and sank in the the Recto Bank allision in June, columnist and special envoy Ramon Tulfo says in a press release. 

"The fishing boat, christened as F/B Pengyou, replaced the F/B Gem-Ver 1 that was sunk at Recto Bank in the South China Sea," the Office of the Special Envoy for Public Diplomacy to China says. Recto Bank is part of the Philippines' exclusive economic zone.

Tulfo says Xue Chengbuao, a tycoon from Shanghai, turned over the the boat in a ceremony in San Jose, Mindoro Occidental on Sunday.

"F/B Pengyou is 17 meters long and 1.6 meters wide. It weighs 10.6 tons and has a Fuso engine with 160 hp," Tulfo's office also says.

"Pengyou" is Mandarin Chinese for friend.

Presidential spokesperson Salvador Panelo says there is no contradiction in the Philippine Coast Guard's report that the June 9 Recto Bank incident is a “very serious maritime casualty” and President Rodrigo Duterte’s earlier statement that the incident was a "little maritime incident."

"It's serious in the sense that when you leave our countrymen there then that's a serious matter," Panelo explains, adding that even if it is a serious matter "you cannot blow that and make it into an international crisis."

He adds the Philippines will "definitely" seek accountability from China over the allision that sank F/B Gem-Ver 1.

He says China will be the one to decide on how it should deal with or make accountable the crew of the Chinese vessel that left 22 Filipino fishermen after the allision.

Vice President Leni Robredo says Senate President Tito Sotto's remark on allowing Chinese to fish within the Philippine EEZ as "the fish could be coming from China" is a bit insensitive, especially to Filipino fishermen whose rights are violated.

"Tingin ko, medyo insensitive siya dahil mayroong mga [mangingisda] tayong na-violate iyong kanilang mga karapatan. Para sa akin, at this point, kailangan nating siguruhin na maramdaman noong mga mangingisda na hindi sila iniwan. Maramdaman nila na tayong lahat nagtutulong-tulong para makahanap sila ng hustisya sa sinapit nila," she says.

Supreme Court Justice Antonio Carpio in a statement says the Philippine government cannot allow Chinese fishermen to fish within the country's exclusive economic zone in the West Philippine Sea as it violates the Constitution.

"The Constitution mandates, 'The State shall protect the nation's marine wealth in its exclusive economic zonem and reserve its use and enjoyment exclusively to Filipino citizens,'" he says.

"This means that the Philippine Government cannot allow Chinese fishermen to fish in our EEZ in the West Philippine Sea. This also means that the 'use and enjoyment' of the fish in our EEZ is reserved exclusively to Filipinos."

More than 200 students, faculty and alumni of the University of the Philippines Visayas – College of Fisheries and Ocean Sciences in Miagao, Iloilo have signed a petition condemning the allision at the Recto Bank in the West Philippine Sea "and the subsequent downplaying of the incident by the Duterte administration."

"We demand full accountability not only on the crew of the Chinese vessel for endangering the lives of the 22 Filipino fisherfolk, but also on the Duterte administration for betraying the trust of our fisherfolk, the constituents whom this government should be protecting and serving," they say in an online petition shared on social media.

The Philippines has filed a diplomatic protest with China over the incident but President Rodrigo Duterte and his officials have played the allision down, calling it a "little maritime incident."

Duterte on Monday night said he is sorry that the crew of the F/B Gem-Ver who were left behind by the Chinese vessel after the allision feel "belittled." He explained that China also considers Recto Bank with its jurisdiction despite it being within the Philippines EEZ. 

"Seeing how the government treats the fisheries sector and the fisherfolk, we are inclined to believe that this administration puts the interest of the Chinese first rather than making the Filipino fishers and WPS a priority," the petitioners say.

"Our fisherfolk are among the poorest and most vulnerable sector in the society. Now, more than ever, is the time to stand in solidarity with them and condemn this blatant turncoatism by the Duterte administration. Let us translate our anger into concrete collective action. Hold Duterte and China accountable," they say.
