"It is also possible that other related issues will be raised," he told a press conference here, Monday.
Anifah said this year with Malaysia as the chair of ASEAN, it was expected three Asean-China Joint Working Group on the DOC and one Asean-China Senior Officials Meeting on the DOC, would be held.
Asean member countries, and China signed the DOC in 2002, a fundamental document for maintaining peace and stability in the South China Sea.
In the declaration, among others, the parties concerned reaffirmed that the adoption of a code of conduct in the South China Sea would further promote peace and stability in the region and agreed to work, on the basis of consensus, towards the eventual attainment of this objective.
Kuala Lumpur had emphasised the need to expeditiously work towards an early conclusion of the Code of Conduct in the South China Sea.
In June last year, Prime Minister Datuk Seri Najib Tun Razak had said that the rule of law must reign supreme in resolving issues in the South China Sea.
The 10 Asean members comprise Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, Brunei and Vietnam.
China and its Asean partners, Malaysia, the Philippines, Vietnam and Brunei have disputes on the overlapping territorial claims in the South China Sea.
On its part, China had said that it was always ready to solve the disputes through dialogues and direct negotiations.
