By Michael Hernandez</p> <p>WASHINGTON (AA) — U.S. President Donald Trump said Wednesday he would be "very, very disappointed" if a report that North Korea is rebuilding a long-range rocket test site is true.</p> <p>Addressing reporters at the White House, Trump said "it’s too early to see" if the report published by Washington-based think tank the Center for Strategic and International Studies (CSIS) and the Korea-focused 38 North website is correct.</p> <p>The group used satellite images that appear to show Pyongyang rapidly reconstructing the Sohae long-range rocket test site in Cholsan County.</p> <p>The study concluded that "North Korea is pursuing a rapid rebuilding of the long-range rocket site at Sohae."</p> <p>The new work began just two days after Trump and North Korean leader Kim Jong-un unsuccessfully concluded a second summit in Hanoi, Vietnam. </p> <p>Sohae had in the past been used to conduct tests of technologies applicable to intercontinental ballistic missiles that North Korea is banned from conducting by the UN Security Council.</p> <p>"It’s a very early report," Trump said. "But I would be very, very disappointed in Chairman Kim. And I don’t think I will be, but we’ll see what happens. We’ll take a look. It’ll ultimately get solved." </p> <p>Trump said his talks with Kim broke down because the North Korean leader wanted the removal of sanctions "in their entirety," a claim rejected by Pyongyang, which insists it merely wanted a partial lifting of the biting economic penalties.
