China, Nuclear | featured news

China's leaders issued thinly veiled rebukes to North Korea for raising regional tensions, with the president saying no country should throw the world into chaos and the foreign minister warning that Beijing would not allow mischief on its doorstep.

An air of cautious optimism hung over Almaty, Kazakstan, on Friday as Western and Iranian negotiators began another round of nuclear talks. The six powers – the United States, Russia, China, France, Britain and Germany – met Iranian officials with the aim of settling a decade-long tussle over Tehran's nuclear program.

Defense Secretary Chuck Hagel is calling North Korea's development of nuclear weapons a "growing threat" to the U.S. and its allies. In a telephone call Tuesday evening to Chinese Defense Minister Chang Wanquan, Hagel cited North Korea's pursuit of nuclear weapons and ballistic missiles and said Washington and Beijing should continue to cooperate on those problems.

It remains unclear just when, if ever, North Korea will attempt their controversial third nuclear test, but there are growing signs that the reclusive nation's biggest political ally is growing weary of its behavior.

China's apparent decision not to block expanded United Nations sanctions against North Korea for its satellite-cum-missile launch last month is good, if mysterious, news. Good, because China has traditionally resisted punishing North Korea for its misdeeds, arguing that engagement is more likely to bring results. Mysterious, because its reasons for changing its mind could be manifold.

White House sources partly confirmed an alarming report that U.S. government computers -- reportedly including systems used by the military for nuclear commands -- were breached by Chinese hackers. “This was a spear phishing attack against an unclassified network,” a White House official told FoxNews.com. “These types of attacks are not infrequent and we have mitigation measures in place.”

Indeed, he suspects that "New Delhi's emphasis on China is more about slighting Pakistan than competing with China." China is already modernising its own nuclear-armed medium- and intermediate-range missile systems that could be used to target India. But as Taylor Fravel notes, "India and China have similar nuclear doctrines, as both emphasize no first use and achieving deterrence through development of a secure second-strike."

India announced plans Wednesday to test launch a new long-range missile, capable of carrying a nuclear warhead as far as the Chinese capital Beijing for the first time. Officials and defense experts said if the tests of the Agni-V missile proved successful, it would mark a significant improvement in India’s nuclear deterrent capability, and would strengthen its hand in a hostile neighborhood, sandwiched between nuclear-armed rivals Pakistan and China.

The United States exempted Japan and 10 EU nations from financial sanctions because they have significantly cut purchases of Iranian crude oil, but left Iran's top customers China and India exposed to the possibility of such steps.

A U.S. envoy will hold talks with North Korea on its nuclear program in Beijing next week, the first such negotiations since the death of the nation's longtime leader, Kim Jong Il.
