China says it will maintain a ban on some Japanese food imports over the plan to release water from the wrecked Fukushima nuclear plant into the ocean.
China's customs administration said it would also implement radiation tests on food from other parts of the country.
South Korea is also maintaining a similar ban but says the proposed release meets international standards.
On Wednesday the UN's nuclear watchdog said it would have "negligible impact" on the environment.
On Friday Japan's nuclear regulator also gave its approval.
In 2011, a tsunami triggered by a magnitude 9.0 earthquake flooded three reactors of the Fukushima Daiichi Nuclear Power Plant. It is regarded as the world's worst nuclear disaster since Chernobyl.
More than 150,000 people were evacuated from an exclusion zone around the plant, which remains in place. Decommissioning of the plant has also started, but the process could take decades.
