WASHINGTON (AP) — The U.S. Defense Department says Burma is still buying conventional weapons from North Korea.

A report to Congress on North Korea’s military capabilities released Wednesday says the secretive nation uses a worldwide network to facilitate arms sales.

It lists Iran, Syria and Burma as a core but dwindling group of recipient countries, but adds that Burma has begun distancing itself from North Korea.

Burma denies violating U.N. sanctions that prohibit such weapons purchases.

The U.S. has pressed Burma’s reformist government to stop buying from North Korea, also previously suspected of supplying Burma with missile technology.

Washington is concerned that North Korea’s arms trade helps bankroll its nuclear and missile programs.

In December, the U.S. blacklisted a Burma military officer and companies for continued weapons trading with the North.
