**US, China Discuss Cyber Security as Dialogue Begins**
The United States and China discussed the sensitive topic of cyber security during the first of four days of talks aimed at expanding cooperation between the two world powers.
U.S. officials say they raised the issue of economic-related hacking during the Monday session in Washington. They also said the two sides discussed international norms for cyber space.
Washington and Beijing agreed in April to hold the working group on cyber security, which has threatened to become a major irritant in bilateral relations.
The Obama administration has accused China of involvement in a broad Internet hacking campaign to steal secrets from U.S. government institutions and businesses for economic gain.
Officials hope to make progress before senior ministers of the two sides hold annual security and economic talks in the U.S. capital Wednesday and Thursday.
Yang Jiechi, a high-ranking Chinese official who is heading Beijing's delegation, says he hopes the dialogue can create more cooperation between the U.S. and China.
**China Trying to Change Regional Status Quo 'By Force:' Japan**
Japan's annual defense paper says an increasingly bold China is attempting to change the regional status quo by force.
The paper adopted Tuesday is likely to be slammed by Beijing, which is involved in a territorial dispute with Japan in the East China Sea.
China has sent regular patrol boats and aircraft near the disputed islands, in what as seen as an attempt to challenge Japan's control of them.
The report called such actions "dangerous" and "extremely regrettable," warning it could cause a "contingency" in the future.
In particular, the paper criticized China for a January incident in which a Chinese navy boat locked its pre-firing radar on a Japanese destroyer. China has denied the claim, calling it inaccurate and provocative.
The white paper is the first released under the current government of hawkish Prime Minister Shinzo Abe, who has taken a firm stance on the island issue since coming to power in December.
