Japanese Prime Minister Shinzo Abe delivers his special address at the opening session of the World Economic Forum in Davos on January 22, 2014.
Japan on Wednesday told the world it must stand up to an increasingly assertive China or risk a regional conflict with catastrophic economic consequences.
In a landmark speech to the World Economic Forum in Davos, Japanese Prime Minister Shinzo Abe issued what amounted to an appeal for international support in a potentially explosive dispute with its superpower neighbour over islands in the East China Sea.
"We must restrain military expansion in Asia ... which otherwise could go unchecked," Abe told the annual meeting of global business and political leaders, which Chinese Foreign Minister Wang Yi is due to attend on Friday.
"If peace and stability were shaken in Asia, the knock-on effect for the entire world would be enormous," Abe added.
"The dividend of growth in Asia must not be wasted on military expansion."
Although Abe did not explicitly mention China, his speech had been flagged up in advance by Japanese officials as an alarm call to an influential audience over what Tokyo sees as bullying by Beijing.
The dispute over the uninhabited but potentially mineral-rich islands is being played out against a backdrop of Japanese fears that China is seeking to exert control over lifeline shipping lanes around its vast coastline and that the United States' commitment to guarantee Japan's security is waning.
