Foreign Minister Yoko Kamikawa met her Chinese counterpart, Wang Yi, on Saturday, with the top Japanese diplomat "strongly urging" Beijing to immediately remove its complete ban on seafood imports from Japan over Tokyo's release of treated wastewater from the Fukushima No. 1 nuclear plant.

The Fukushima issue has bedeviled Sino-Japanese relations already facing tensions over issues such as China's growing military assertiveness in the region. Despite this, both sides agreed to find a way to resolve the wastewater matter "through discussion and dialogue in a constructive manner," Japan's Foreign Ministry said.

Wang repeated China's opposition to the discharge of "nuclear-contaminated water," a move that he labeled as "irresponsible," according to the Chinese Foreign Ministry.
