Chinese President Xi Jinping may soon meet with his Japanese counterpart on his trip to attend the Asia-Pacific Economic Cooperation summit.
Beijing and Tokyo are making final arrangements for Xi to hold talks with Prime Minister Kishida Fumio.
China's suspension of Japanese seafood imports will likely be high on the agenda.
The two last held talks about one year ago, well before China imposed the restriction in August, in reaction to Japan's release of treated and diluted water from the Fukushima Daiichi nuclear power plant into the ocean.
China imported about 56 million dollars' worth of Japanese seafood in September last year. That number dropped by more than 90 percent in the same month this year.
Exports of key products like scallops, sea cucumbers and tuna fell to zero.
Analysts are watching to see whether the meeting leads to progress on the issue, as well as others such as China's detention of Japanese nationals for alleged spying activities.
