China says it will ban North Korean coal and other goods under U.N. sanctions 

China announced Monday that it will cut off imports of North Korean coal, iron ore and other goods in three weeks under U.N. sanctions imposed over the North’s nuclear and missile programs.

China, the isolated North’s main trading partner, has been reluctant to push leader Kim Jong Un’s regime too hard for fear it might collapse. But Beijing is increasingly frustrated with Pyongyang and supported an Aug. 5 U.N. Security Council ban on importing North Korean coal and other key goods.

The Chinese customs agency said it will stop processing imports of North Korean coal, iron and lead ores and fish at midnight on Sept. 5.

“After that, entry of these goods will be prohibited,” said an agency statement.

The announcement follows an escalating exchange of angry words between President Trump and Kim’s government. Trump declared the U.S. military “locked and loaded” while Pyongyang threatened to fire four missiles into waters near the U.S. territory of Guam.

On Monday, the top U.S. military officer told his counterparts in South Korea on Monday that the United States is ready to use the “full range” of its military capabilities to defend itself and its allies from any North Korean provocation.

Marine Corps Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, is visiting South Korea, Japan and China, and earlier told reporters traveling with him that he aimed to “sense what the temperature is in the region.”

“We’re all looking to get out of this situation without a war,” Dunford said.

The latest U.N. sanctions are intended to block North Korean exports worth $1 billion — a significant share of total exports valued at $3 billion last year.

China stopped importing North Korean coal in February but total trade has risen, which prompted Trump to accuse Beijing in July of failing to use its economic leverage to stop Pyongyang’s pursuit of nuclear weapons.

Beijing had long been Pyongyang’s only diplomatic defender but agreed in March 2016 to sanctions against the North following its test of a long-range missile.

Still, Chinese leaders oppose blocking all trade with the impoverished North, which they argue might cause widespread hunger.

The Chinese import cut will come the week of Foundation Day on Sept. 9, the North Korean holiday commemorating the founding of the country’s government in 1948.

In the first half of this year, North Korean imports of Chinese oil, consumer goods and other products rose 36.7% from a year earlier, to $165 million, according to Chinese customs data. Chinese imports from the North fell 7.6% in the same period to $91 million, squeezing the North’s revenue.
