Dandong Hongxiang Industrial Development Co. Ltd. Logged more than USD 530 million in two-way trade with North Korea between 2011 and 2015, the Asan Institute for Policy Studies in Seoul and C4ADS in Washington said in a report released yesterday.
Information in online advertisements and databases show that the company sold pure aluminium ingots, aluminium oxide and other products that could qualify as potential military and nuclear dual use products under US export restrictions, it said.
"While no judgement is being made on the final use of these funds, trade at this volume is of particular note," it said.
"By one estimate, this amount would have been almost enough to both fund North Korea's uranium enrichment facilities and to design, make, and test its nuclear weapons," it said.
Liaoning's public security department said in a statement last week that they have placed Dandong Hongxiang and its bosses under investigation for "serious economic crimes involved in trade activities".
The company did not respond to phone calls from AFP seeking comment.
Asked about the investigation during a regular press briefing, China's foreign ministry spokesman Lu Kang said that "relevant departments in China are handling and investigating this case", but would not confirm whether there was a connection to Pyongyang's nuclear programme.
But Beijing has been increasingly frustrated by Pyongyang's defiance of international sanctions to press ahead with its nuclear tests.
