President Trump said Friday that negotiations with North Korea over its nuclear program were going great — despite a new report that the rogue regime has thumbed its nose at the president and the UN by blatantly transferring oil imports at sea in violation of sanctions banning the transfers.

“Many people have asked how we are doing in our negotiations with North Korea — I always reply by saying we are in no hurry, there is wonderful potential for great economic success for that country,” the commander-in-chief tweeted.

“Kim Jong Un sees it better than anyone and will fully take advantage of it for his people. We are doing just fine!”

But NBC News, citing “a Top Secret” Pentagon assessment, said the oil transfers were continuing despite UN sanctions and Trump’s efforts to pressure China, Russia and other countries that export oil to the regime from violating them.

The smuggled fuel helps Kim Jong Un’s impoverished country continue to function in the face of intense US pressure aimed at forcing the dictator to abandon his nuclear weapons program.

The US Pacific Command assessment, labeled “Top Secret,” found that warships and surveillance aircraft deployed by an eight-nation coalition since September had forced Pyongyang to tweak its tactics at sea, including transferring oil farther away from the Korean peninsula and often in other nations’ territorial waters, the network reported, citing a trio of top military officials.

The crafty North Koreans are also using smaller vessels to avoid being recognized by the coalition’s warships and aircraft, the officials said.

But the assessment also determined that while transfer attempts have not decreased, the coalition has forced the North Koreans out of the East China Sea and into waters to the north and south.

The US began surveillance flights over the East China Sea to disrupt the illicit transfers in October 2017, and has flown 300 flights between then and now.

Allied nations began flights April 30, and have flown more than 200 surveillance flights to date, according to the report.

“We’ve increased pressure and have been collecting information on these illicit transfers and then feeding them back to our interagency partners for financial, law enforcement and diplomatic action,” one official told NBC News.

In September, the coalition — Australia, Britain, Canada, France, Japan, South Korea and New Zealand — expanded surveillance of the smuggling by deploying warships and aircraft to spot violations.

Trump — who said in October that he and Kim “fell in love” during their summit — has declared that the North had agreed to end its nuclear program.

But while known missile tests have been stopped, the rogue regime continues building weapons and increasing its arsenal, according to multiple reports.

The North also continues to import black market oil, often with the help of US rivals China and Russia.

And a report by UN sanctions experts in August, based on US intelligence, found the number of transfers surging, with vessels turning off the transponders that show a ship’s geographic location, the network said.

“It’s a sustained effort, but I would tell you the North Koreans are learning, evolving, getting better, so the ship-to-ship transfers are taking place farther away from the peninsula,” Randy Schriver, assistant secretary of defense for Asian and Pacific security affairs, said at a discussion this month at the University of Chicago.

“So they’re getting better with their own attempts to evade, and we’re evolving as well in terms of our sustained effort to disrupt that.”

The crew of a Canadian navy ship, the HMCS Calgary, reportedly saw several ship-to-ship oil transfers in recent months in the East China Sea, with suspected blacklisted vessels taking part.
