North Korean relations to its biggest supporter have cooled due to the recent nuclear tests.
Just half a year ago, China enthused that North Korea is a great place for investment. Since then the country conducted a nuclear test, as well as launched a long-distance missile, and the Chinese opinion has changed.
Chinese newspapers call on North Korea to be a thankless and unstable risk factor. Businessmen no longer desire to even mention the country in their speeches.
China has not, at least not yet, cancelled its official partnership for its communist partner, but the countries are no longer "thick as thieves".
- In my opinion, China's policy toward the Korean peninsula has had a significant and recognizable change, says Beijing University International Security Training Program director Zhu Feng.
According to Zhu, China is confident that the diplomatic sanctions to North Korea will change the country to alter its behavior.
- Beijing has finally woken up to reality.
In the UN Security Council, Beijing turned visibly in favor of tough sanctions against North Korea.
Earlier, China has opposed the sanctions planned against North Korea, and even on last Saturday, Foreign Minister Yang Jiechi said that the sanctions cannot solve the current situation.
The nuclear test made by North Korea on Tuesday, however, eventually changed the opinion of China, and the country negotiated with Washington about the new sanctions. On Thursday it was announced that the sanctions will be tightened, with all cargo going to the country will be strictly inspected and exporting luxury goods will be greatly restricted.
China is also frustrated because it has not been able to guide Pyongyang towards economic prosperity.
One of the issues is also the fact that North Korean leader Kim Jong-un has not yet sworn his "peasant"-oath to China at all, unlike his father and grandfather. Kim Jong-un has not visited China after the death of his father.
Previously, China felt slight sympathy for the Korean War-era brother-in-arms, but now, as China's economic power grows, North Korea is thought of derisively and the country is blamed to be incapable of understanding.
Even the Communist Party propaganda-tabloid, The Global Times, urged China to break off relations with North Korea completely.
"This China-North Korea "friendship"does not depend on the current mood of Pyongyang at all", the Journal wrote in an editorial.
