SEOUL (Reuters) - North Korea issued a rare reproach of China on Thursday saying its main diplomatic backer was "dancing to the tune" of the United States for halting North Korean coal imports because of its nuclear and missile programs.
The North's state-run KCNA news agency did not refer directly to China by name but in an unmistakable censure it accused a "neighboring country" of going along with North Korea's enemies to "bring down its social system".
"This country, styling itself a big power, is dancing to the tune of the U.S. while defending its mean behavior with such excuses that it was meant not to have a negative impact on the living of the people in the DPRK but to check its nuclear program," KCNA said in a commentary.
China said on Saturday it would ban coal imports from North Korea, which is officially known as the Democratic People's Republic of Korea (DPRK), until the end of the year.

The ban came about a week after North Korea tested an intermediate-range ballistic missile in its first direct challenge to the international community since U.S. President Donald Trump took office.
Trump's administration has said China should do more to put pressure on North Korea.
"A neighboring country, which often claims itself to be a 'friendly neighbor', is .. threatening that 'the DPRK will suffer the biggest loss'," KCNA said in the commentary.
"It has unhesitatingly taken inhumane steps such as totally blocking foreign trade related to the improvement of people's living standard under the plea of the U.N. 'resolutions on sanctions' devoid of legal ground."
China is North Korea's sole major ally but it disapproves of its nuclear program and has backed U.N. sanctions against it. China calls for the Korean peninsula to be free of nuclear weapons.
North Korea has conducted five nuclear tests, including two last year, although its claims to be able to miniaturize a nuclear weapon to be mounted on a missile have never been verified independently.
North Korean leader Kim Jong Un said in a New Year speech the North was close to test-launching an intercontinental ballistic missile. State media has said such a launch could come at any time.
A fully developed ICBM could threaten the continental United States, which is about 9,000 km (5,500 miles) from North Korea.
North Korea was China's fourth biggest supplier of coal last year, with non-lignite imports reaching 22.48 million tonnes, up 14.5 percent compared with 2015.
