Chinese President Xi Jinping urged world leaders to respect each country's sovereignty over its own Internet as he sought broader support for strict controls like China's on Wednesday.

The international community must respect each country's internal affairs, Xi told a global technology gathering Wednesday in Wuzhen, eastern China, applying to the Internet a concept that long has been a part of the Communist Party's foreign policy. He also said cyberspace must not become a "battlefield" between states and called for greater cooperation on punishing cyberattacks and fighting terrorism.

"There should be no double standards in safeguarding Internet security," Xi said. "A country should not harm another's security for the sake of its own security. Some countries should not seek security at the expense of others, let alone sacrifice others' security to seek absolute security."
