By Liz Lee and Sakura Murakami BEIJING/TOKYO (Reuters) -Seafood trade is expected to be on the agenda on Wednesday as Japan's foreign minister visits China, Japan's largest export market for aquatic products until Beijing banned them in protest against Tokyo releasing treated radioactive wastewater into the ocean.

China and Japan agreed that Beijing’s top diplomat should visit in 2025, adding to the signs the two nations are repairing ties that have been strained in recent years.

Japanese Foreign Minister Takeshi Iwaya has met with top Chinese leaders during his visit to Beijing, the first since the heads of the two countries met at a summit in Peru last month
