China rejected Japan's accusation over withholding information about its nuclear policy on Tuesday, saying the accusation was groundless.

Jiang Yu, spokeswoman of Chinese Foreign Ministry, told a regular press conference that China had all along advocated and positively supported the comprehensive ban on nuclear weapons and complete nuclear disarmament.

Japanese Foreign Minister Hirofumi Nakasone accused China of withholding information about its nuclear weapons while delivering a speech in Tokyo on Monday.

The speech, entitled "Conditions towards Zero -- 11 Benchmarks for Global Nuclear Disarmament", came in supportive response to the remarks made on April 5 by U.S. President Barack Obama, who advocated a world without nuclear weapons and declared Washington's "moral responsibility to act" to that end.

"China supports the process of international nuclear disarmament, and has made unremitting efforts for it," said Jiang.

Jiang also stressed that China's nuclear policy was clear and transparent. "Japan's accusation is completely groundless."

But Jiang said China's ties with Japan were at an important period to build a mutually beneficial relationship and further enrich its content.

She made the remarks when asked to comment on Japanese Prime Minister Taro Aso's upcoming visit.

Aso will pay an official visit to China from April 29 to 30 at the invitation of Chinese Premier Wen Jiabao.

"We attach great importance to this visit," Jiang said, hoping that this visit would help increase mutual trust in politics and expand cooperation in various areas, in a bid to promote the healthy and stable growth of Sino-Japanese relations.

China also hoped the two sides would discuss how to jointly cope with the international financial crisis during Aso's visit, Jiang noted.
