Kim Jong-un's regime has flouted international sanctions and its nuclear program continues

North Korea's nuclear weapons and ballistic missile programs remain intact, and Pyongyang uses airports and other facilities to protect its weapons before possible enemy bombing, said Tuesday a panel of UN experts in a report sent to the Security Council.

The sanctions against the Asian country were "ineffective", according to the authors of the document to which the agency had access AFP. The regime of Kim Jong-un acquired illegal shipments of petroleum products, sold coal, despite the ban imposed by the UN, and violated an arms embargo.

"The nuclear and ballistic missile program of the Democratic People's Republic of Korea remains intact," the report said. "The panel found that North Korea uses civilian facilities, including airports bademble and test ballistic missiles in order to effectively avoid "decapitation" bombings. "

The United Nations Security Council received the report when the US President, Donald Trump, is preparing to hold a second summit this month with Kim Jong-un, in the hope of progressing in the denuclearization of North Korea, one of the commitments made at the first meeting between the two leaders.

The US administration pushed hard economic sanctions against North Korea to the UNin retaliation for its nuclear tests and several ballistic missile launches in 2017.

But the country realized Illegal trade in oil, gasoline and coal use a network of ships to circumvent the sanctions with which they sought to deprive him of the revenues necessary to continue his weapons programs.

"These violations render the latest UN sanctions ineffective", says the report.

According to UN resolutions, North Korea can not import more than four million barrels of crude a year and 500,000 barrels of refined oil.

North Korea also violates the arms embargo and tried to sell small arms to Syria, the UN experts wrote to Houthi rebels in Yemen, Libya and Sudan.

And financial sanctions "are among the worst measures applied," they added, referring to a transfer of European bank accounts to Asia.
