North Korea said Wednesday that it has conducted successful cruise missile tests, the latest display of its growing military capabilities and one that comes while U.S. President Donald Trump visits South Korea.

President Donald Trump noted that he'd be willing to extend his trip to meet with Kim Jong Un of North Korea, if the foreign official wants to meet.

U.S. President Donald Trump arrived in South Korea Wednesday, where he said he wasn't able to "work out timing" for a meeting with North Korean leader Kim Jong Un.

But President Donald Trump ’s back-to-back announcements about nuclear testing and nuclear submarines on Oct. 29 during his trip to South Korea could turn the nuclear weapons world upside down.

The launches follow North Korea’s tests of short-range ballistic missiles last week, which it said involved a new hypersonic weapon intended to bolster its nuclear deterrent.

U.S. President Donald Trump made repeated invitations to meet North Korean leader Kim Jong Un as he prepared to visit South Korea this week, with officials in Seoul serving as his cheerleaders.

The U.S. will share closely held technology to allow South Korea to build a nuclear-powered submarine, President Donald Trump said ahead of a meeting with China’s leader Xi Jinping.

President Trump has announced plans to begin testing nuclear weapons, raising fears of a new arms race as Russia and China respond with warnings.
