MANILA (Reuters) - Philippine President Rodrigo Duterte said on Sunday he would raise a controversial arbitral ruling on the South China Sea with China's leaders, and vowed not to surrender any sovereignty or deviate from the July award by the tribunal in The Hague.

Duterte said his trip to China this week represented a turning point in bilateral ties, but he acknowledged there was some public concern about his rapid rapprochement moves and reassured Filipinos that would not impact on the country's maritime sovereignty.

In comments that will not sit comfortably with the Chinese leadership, Duterte said the decision by the Permanent Court of Arbitration would be talked about and the parameters of the award would be discussed, but there would be no "hard imposition" of it.

The ruling dealt a blow to China's extensive claims in the South China Sea. Beijing has refused to recognize the case and has chided any country telling it to abide by the ruling.

"I will not bargain anywhere, we will continue to insist that is ours," he told a news conference in his home city of Davao.

"The international tribunal decision will be taken up."

The unpredictable president's moves to strongly engage China, just a few months after an arbitral award that sparked fears in the region of a backlash by Beijing in the South China Sea, mark a striking reversal in Philippine foreign policy since he took office on June 30.

Duterte goes to China on Tuesday with at least 200 members of the Philippine business elite to pave the way for what he calls a new commercial alliance. Among the areas expected to be prioritized are financing for Philippine businesses, farm exports, major infrastructure investments and tourism.

It comes amid a torrent of anti-American comments by Duterte that have cast a cloud over a longstanding relationship with the United States.

While he continues to chastise and hurl abuse at Washington for expressing concern about his bloody war on drugs, he insists his strategic gambit is about abiding by a constitution that enshrines an independent foreign policy.

He spoke of his intention to "intensify" trade ties and work closer with China, but would not avoid discussing what is a bone of contention between them.

"There will be no hard impositions. We will talk, we will maybe paraphrase everything in the judgment and set the limits of our territories, the special economic zones," he said of meeting.

"It will be no bargaining. It is ours and many of you are wanting to ask the question. No bargaining."

Duterte's comments might rattle China, which has spoken glowingly about the new partnership, but may not want to hear about an international ruling that it lost comprehensively, and included the invalidation of the U-shaped "nine-dashed line" featured on Chinese maps and passports.
