French President Nicolas Sarkozy has called for clear international standards on nuclear safety in light of the ongoing¹ crisis at Japan's Fukushima Daiichi nuclear plant.

鉴于目前日本正在发生的福岛核电站辐射危机，法国总统尼古拉·萨科奇呼吁对核安全制定清晰的国际标准。

Speaking in Japan, he proposed that nuclear safety authorities from the G20 countries discuss the issue in May.

Radiation detected in the sea near the stricken plant has again risen steeply.

Meanwhile, the UN has advised Japan to consider expanding the evacuation zone around the reactors².

Mr Sarkozy is the first foreign leader to visit Japan following the earthquake and tsunami³ that hit the country on 11 March.

The disaster has so far claimed more than 11,000 lives, with at least 16,000 people still reported missing.

The French president said he wanted to see international standards on nuclear energy established by the end of the year, and that France would ask G20 nuclear delegates to lay the groundwork for a special meeting of the International Atomic Energy Agency (IAEA) in June.

"The problem is more about establishing safety norms than it is about the choice of nuclear energy, for this there is no alternative right now," Mr Sarkozy was quoted as saying by Reuters.

"We must address this anomaly（异常，不规则） that there are no international safety norms for nuclear matters. We want international standards because the world is a village and what happens in Japan can have consequences elsewhere."
