"I want to improve Japan-China relations," Abe told reporters at Tokyo's Haneda airport.
"For a summit (with Xi), the final arrangements still need to be made. But if it is to take place, I would like to give my message that Japan and China -- responsible for the international community's peace and stability -- develop their bilateral ties... As well as starting a maritime communication mechanism to avoid accidental collisions."
Abe heads to Beijing for APEC after Japan and China reached an accord on Friday to tone down tensions over territorial and historical disputes that had fuelled concerns of outright conflict.
Tokyo has long been pressing for a meeting. But Beijing has resisted, with the two sides locked in a row over the Tokyo-controlled Senkaku islands -- which China calls the Diaoyus -- and also still at odds over World War II history.

The talks between Wang Yi and Fumio Kishida were the first at such a level since September 2012, just before the territorial dispute escalated with Japan's nationalisation of the islands.
Since then, Chinese vessels and aircraft have regularly approached the islands, with Japan's coastguard in hot pursuit.
In the accord between the two announced Friday, each used only their own name for the islands but said they would set up a "crisis management mechanism" to keep the situation under control.
