"China's stance on [this matter] is consistent," Foreign Ministry spokesman Hong Lei told a media briefing here.
His comments came after Japanese Prime Minister Shinzo Abe delivered a speech at the UN General Assembly and sought international community's support for Tokyo's application for a permanent seat at the UN Security Council.
Japan along with India, Brazil and Germany made a strong bid in recent years for expansion of the current list of five permanent members in the 15-member UNSC, the most powerful body of the UN system.
Hong said UNSC reform concerns the UN's long-term development and the vital interests of its 193 member states.
He said all UN members, including those aspiring to play a bigger role at the UNSC, should first respect history and not challenge the accomplishments of the world's anti-fascist war.
While China was explicit in its opposition to Japan's bid for UNSC permanent member seat, it has remained non-committal about India's bid maintaining that it recognises New Delhi's aspiration to play a bigger role in the UNSC.
