North Korea sent a letter to the U.S. House of Representatives expressing their displeasure with the recent round of sanctions passed.
The foreign affairs committee of the North's Supreme People's Assembly condemned the sanctions as a “heinous act against humanity.”
While Pyongyang does speak out against Washington’s moves to censure the regime, Fox News reports that sending a direct letter protesting the sanctions is rare.
It was not immediately clear how the protest was conveyed since North Korea and the United States have no diplomatic relations and virtually no official channels of communication.
The report, carried by the North's Korean Central News Agency, said the letter of protest was sent Friday.
The sanctions package bill, which was imposed over the regime’s weapons programs, was passed in the House by a vote of 419-1.
The bill targets North Korea’s shipping industry and use of slave labor. Additionally, it requires the Trump administration to decide within 90 days whether North Korea should be put back on the government’s state sponsors of terror list. If the administration decides to do this more sanctions would be triggered.
