Chinese President Xi Jinping is to attend the meeting of APEC, which includes the United States, China, Japan, South Korea, Indonesia and Canada and together accounts for 57 percent of global production and 46.5 percent of world trade.
"Everyone knows that APEC is primarily about discussing trade and financial cooperation in the Asia Pacific," Chinese Vice Foreign Minister Li Baodong told reporters in answer to a question.
"As far as I know, at this year`s summit, there are no plans to discuss the South China Sea."
China has overlapping claims with Vietnam, the Philippines, Malaysia, Taiwan and Brunei in the South China Sea, through which $5 trillion in ship-borne trade passes every year.
A summit of the Association of Southeast Asian Nations last week, attended by both the United States and China, failed to produce a final statement because the delegations could not agree on whether to mention the South China Sea dispute.
China has been particularly angered by a case lodged by the Philippines with an arbitration court in the Netherlands over the South China Sea. China says it will neither recognize nor participate in the case.
Philippine Foreign Secretary Albert del Rosario met Chinese Foreign Minister Wang Yi in Manila for the first high-level talks between the two neighbors since 2011.
"They expressed hope the contentious issues will not be raised (at APEC) and we said we will endeavor on our side not to raise contentious maritime issues," Charles Jose, Manila`s foreign ministry spokesman, told a news conference.
He said Manila would not raise the South China Sea issue because of the arbitration case in The Hague and because APEC was "not the proper forum".
Separately, China`s Defence Ministry said that naval chief Wu Shengli had left for a visit to Malaysia and Indonesia. It gave no other details.
Malaysia, another claimant in the South China Sea, has taken an increasingly vocal position on the dispute of late.
