"firmly" opposed to North Korea's third nuclear test and called for a denuclearisation for peace in the Korean Peninsula.
Chinese foreign minister Yang Jiechi also summoned Democratic People's Republic of Korea ambassador to China, Ji Jae Ryong, on Tuesday to lodge a solemn representation.
Yang said China was "strongly dissatisfied with" and "firmly opposed to" DPRK's third nuclear test, according to a press release issued by the Chinese foreign ministry.
The commentary, published in the state-run Xinhua news agency, however said that at a superficial level, "…it was Pyongyang that has repeatedly breached UN resolutions and used its nuclear program as a weapon to challenge the world community, which was considered to be unwise and regrettable."
"Pyongyang said it conducted the third underground nuclear test to defend its national security and sovereignty against hostile US policies and protest against a UN Security Council resolution, pushed through by Washington last month to punish the DPRK (Democratic People's Republic of Korea) for its satellite launch in December," it said.
In reality, the commentary added: "the DPRK's defiance was deeply rooted in its strong sense of insecurity after years of confrontation with South Korea, Japan and a militarily more superior United States."
It added that in the eyes of the DPRK, Washington has spared no efforts to contain it and flexed its military muscle time and again by holding joint military drills with South Korea and Japan in the region.
"The latest nuclear test is apparently another manifestation of the attempt of a desperate DPRK to keep threat at bay," the commentary said.
It has come to a point for all parties concerned to think and act rationally to create favorable conditions to revive the long-stalled six-party talks and avoid disastrous fallout.
The Chinese foreign minister told the same thing to US secretary of state John Kerry when they held talks on the nuclear test late on Tuesday.
During the talks, Yang said China has explicitly stated its position on the DPRK's nuclear test.
China called on all parties concerned to keep focused on the overall situation, deal with the issue properly, and prevent the situation from escalating, he added.
"All parties concerned should stick to the direction of a peaceful solution, resolve the issue of denuclearisation of the Korean Peninsula within the framework of the six-party talks, and safeguard peace and stability on the peninsula and in Northeast Asia at large," Yang was quoted by state media as having told Kerry.
