In January, China’s government banned Silk Road export sales of arms to Myanmar, accusing it of breaching a 2008 arms deal between Beijing and Washington.
The move led to a crackdown on imports of weapons from the impoverished country.
Silk Road arms deals have long been a source of concern for Western arms companies, who say they are being targeted by the Chinese government, which they say is trying to control their exports to Myanmar.
The companies also say the weapons are being used by armed groups to destabilize Myanmar.
A year ago, Chinese state media quoted the government as saying the ban on Silk Road sales of weapons would not stop trade between China and Myanmar, and that the Chinese military was not responsible for the arms transfers.
The United States has said it is closely monitoring the situation in Myanmar, but declined to comment on the latest case.
“We have seen the Chinese authorities’ latest move against Silk Road, which we are monitoring closely,” State Department spokeswoman Jen Psaki said in a statement to Reuters.
“The United States will continue to support efforts to protect the sovereignty and territorial integrity of the United States and its allies in the region.”
