Another Chinese research vessel docks in Davao City

Metro Manila (CNN Philippines, September 1) — Another research vessel of the Chinese government has docked at a port in Davao City, less than two months after a Chinese ship made a call there.

Major Ezra Balagtey, spokesperson of the military's Eastern Mindanao Command, on Saturday confirmed that Yuan Wang 7 dropped anchor at Sasa Wharf on Friday.

Balagtey said the ship is expected to leave on Monday and is staying at the port "for replenishment."

"Her stay in the Philippines is subject to the conditions as stated through Diplomatic Note issued by DFA (Department of Foreign Affairs)," Balagtey told reporters in a text message.

In July, another Chinese research and surveillance ship, Yuan Wang 3, also docked at Sasa Wharf. Defense Secretary Delfin Lorenzana then said there was "nothing unusual" in the port call, saying the ship would only replenish supplies.

Retrieving PH frigate

Meanwhile, retrieval operations are underway for BRP Gregorio del Pilar, the Philippine Navy's flagship that ran aground at a shoal in the disputed South China Sea on Wednesday night.

Reports said China has sent Coast Guard and rescue vessels to help with the retrieval operations, but the Philippine Navy said it was not informed of such moves. The Armed Forces also said the Philippines can do it alone.

"We did not ask for help from anybody... We can on our own, we can resolve this one," Armed Forces Public Affairs Chief Col. Noel Detoyato told reporters in a phone interview Friday.

Malacañang refused to speculate on what China would do in response to the grounding incident.
