CHINA’S, Japan’s and South Korea’s foreign ministers met today at the South Korean city of Busan in a bid to revive trilateral co-operation following a four-year hiatus.

They agreed to resume their leaders’ trilateral summit — but without a specific timing.

And tensions between the three were centre-stage, as China and Japan clashed over the latter’s release of treated radioactive wastewater into the sea from the ruined Fukushima Dai-ichi nuclear plant, which has prompted a Chinese ban on Japanese seafood imports.
