BEIJING - China has released a list of technologies and goods banned from export to North Korea because of their possible use in building nuclear, chemical and biological weapons, China's Ministry of Commerce said on Monday.
China and other members of the United Nations have declined in the past to give a full list of items banned from export, a situation that UN monitors say has made difficult the task of determining whether Beijing is really implementing sanctions.
"It means China is strictly complying with the UN Security Council resolutions," said Zhang Liangui, an expert on North Korea at China's Central Party School.
"Frankly, since North Korea conducted the third nuclear test in February, China has begun to adjust its policy toward North Korea, including prohibiting exports of dangerous products."
China is North Korea's sole major ally but it criticised the North's nuclear test in February. China has repeatedly called for the denuclearistion of the Korean peninsular.
China was also frustrated with North Korea's threats against South Korea and the United States after the imposition of new UN sanctions following the nuclear test.
China signed on to those UN sanctions but it remains North Korea's largest trading partner and the United Nations has criticised it for failing to enforce trade bans on the North.
China has also come under pressure, especially from the United States, to moderate its support for the North.
The 236-page list names dozens of products known as "dual-use technologies," meaning that although ostensibly meant for civilian purposes, they can be used in military programmes.
