President Duterte might raise the Recto Bank issue at the coming summit of the Association of Southeast Asian Nations (ASEAN) in Thailand as part of talks on the Code of Conduct in the South China Sea, a ranking foreign affairs official said yesterday.

Contrary to the previous remarks of Defense Secretary Delfin Lorenzana, Malacañang said Chinese Ambassador Zhao Jianhua will not be summoned over the incident in Recto Bank.

Following the sinking of a Filipino boat by a Chinese vessel, the Philippines' top diplomat called on the international community to render assistance to persons in distress at sea.

Foreign Affairs Assistant Secretary Junever Mahilum-West said the South China Sea will be on the ASEAN Summit's agenda.

Beijing reiterated that the collision between the two boats near Recto Bank was "accidental."
