China distances itself from North Korea.

North Korea sent a top aide to Kim Jong Il to Beijing the same day it was leaked U.S. diplomatic offices show that China is increasingly willing to consider the unification of Korea under the control of the South.

Choe Thae Bok, chairman of North Korea's Supreme People's Assembly, left for Beijing today for talks with Chinese leaders, the state-run Central News Agency of Korea reported. Choe met with China's President Hu Jintao in China's capital October 2 Kimon accompanied a trip to the city in May, according to KCNA.

Choe visit comes after China proposed on 28 November that the negotiators of the two Koreas, Japan, Russia and USA meet in Beijing next month to ease tensions after an artillery attack on 23 November North Korea on an island in South Korea, which killed four people. A U.S. Navy carrier aircraft is conducting exercises in the Yellow Sea off the coast of Korea.

Japan rejected China's proposal yesterday. The conversation is not only North Korea out of control'','' Japanese Foreign Minister Seiji Maehara, Wall Street Journal said in an interview. Nicholas Snyder, a spokesman for the U.S. Embassy in Beijing, said that "clearly the steps North Korea are required to demonstrate a change in behavior." said the South Korean Ministry of Foreign Affairs and Trade would consider China to call for caution conversaciones''con. ''

China is the largest North Korean trading partner and source of much of the country's food, fuel and foreign currency. The two countries have been allies for 60 years since fighting together against the US-led forces during the Korean War of 1950-53. The two countries share a 1,415 kilometer (880 mile) border.

Unreliable

A leak of 22 February diplomatic cable provided to The Guardian by WikiLeaks.org said the then minister of South Korea's Deputy Foreign Minister Chun Yung Woo said U.S. Ambassador Kathleen Stephens, the young Chinese Communist Party leaders do not think North Korea is a reliable ally. Chun also said that two unidentified Chinese officials said they believed that Korea must be unified in the South.

U.S. Secretary of State, Hillary Clinton said yesterday Obama "strongly condemns" the unauthorized release of more than 250,000 documents that Wikileaks diplomats began publishing two days ago. State Department spokeswoman Nicole Thompson said he "can not give veracity of Wikileaks has posted anything to the media" and said the agency's policy is to refrain from commenting on certain filtering materials.

China hopes U.S. will "properly handle" the situation created by the filtered messages, Foreign Ministry spokesman Hong Lei, told reporters in Beijing.

South Korean foreign ministry spokesman, Kim Young Sun said it would be "inappropriate to comment on the documents of other countries diplomatically.

'Regrettable'

''While the details of diplomatic discussions have been leaked, it is regrettable,''said Kim.

U.S. China is pushing to censure North Korea for the bombing of Yeonpyeong island. China has avoided blame his partner of 60 years instead of criticizing joint naval exercises in South Korea and the U.S. in the Yellow Sea, which began Nov. 28.

Chun, now national security adviser to South Korea, said Stephens China''tiene much less influence than most people cree''sobre the regime of Kim Jong Il, according to the February 22, quoted in The Guardian cable , a UK newspaper.

Chinese officials told U.S. diplomats that their efforts to persuade North Korea had been rejected, and that the U.S. was the only country with real influence, as an escape wire for June 17, 2009. "The United States was the key, while China was only able to apply a little oil to the lock, the cable quoted a unnamed Chinese official as saying.

'Darling'

A separate message from Beijing, said China's Vice Foreign Minister He Yafei, in April 2009, an American diplomat said that North Korea tests missiles were designed to capture the attention of the U.S. and that the Pyongyang government was actuando''como a spoiled child. "Two months later, U.S. Ambassador to Kazakhstan Richard Hoagland, sent a wire saying that his Chinese counterpart, Cheng Guoping, said that North Korea was a" threat to world security, "said The Guardian.

The cables are above all an increase in diplomatic activity between China and North Korea this year.

Kim made an unprecedented two visits to China this year, meeting with President Hu Jintao, on both occasions. In October, Zhou Yongkang, member of China's ruling Politburo Standing Committee, was with Kim at a military parade in Pyongyang. Later that month, top Chinese general Guo Boxiong visited North Korea, marking the two countries "victory" over the forces of "imperialism" led by the United States during the Korean War of 1950-53.

China also failed to criticize or blame North Korea for the March sinking of a warship in South Korea. An international panel found evidence that North Korea torpedo was responsible for the collapse, which killed 46 sailors.

WikiLeaks.org, a nonprofit group that released the information that governments and companies want to keep secret, has over the last two days posted on its website what it says are secret, confidential or, in some unclassified cases leads the U.S. embassy.
