China marked the 78th anniversary of its World War Two victory over Japan on Sunday. The Japanese Embassy in Beijing reported no rallies near its compound to protest Japan's release of treated and diluted water from the Fukushima Daiichi nuclear power plant into the sea.

In 2014, China designated September 3 as "the Anniversary of the Victory of the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War." Japan signed documents of surrender on September 2, 1945.

State-run China Central Television reported that people attended a symposium to commemorate the anniversary on Sunday. CCTV said the participants included Li Shulei, who heads the Publicity Department of the Chinese Communist Party's Central Committee.

The broadcaster said they discussed the significance of the war victory. But it did not refer to the water release.

Officials at the Japanese Embassy in Beijing say no protests against the water discharge took place amid a heavy presence of police officers around its premises.

But the officials are calling on Japanese nationals in China to stay on guard as anti-Japan sentiment also tends to grow on other dates.

Many online postings in China are still criticizing the water discharge.

The Fukushima Daiichi plant suffered a triple meltdown in the 2011 earthquake and tsunami. Water used to cool molten fuel at the plant has been mixing with rain and groundwater.

The accumulated water is treated to remove most radioactive substances, but still contains tritium.

Before releasing the treated water into the sea, the plant's operator dilutes it to reduce tritium levels to about one-seventh of the World Health Organization's guidelines for drinking water.
