A scud missile landing in Japanese waters. Just as state media showed Kim Jong-un inspecting his new anti-aircraft system, smiling -- president trump today condemning a defiant regime. North Korea has shown great disrespect for their neighbor, China, by shooting off yet another ballistic missile, but China is trying hard! Reporter: But despite China's mild pressure, it's not enough. We traveled along North Korea's 80 on-mile border. This is China and right there is North Korea, darkness. Reporter: The two countries still trading partners but tension is growing, security tighter. Tonight, the threat remains that North Korea will one day be able to reach the U.S. Mainland with a nuclear missile. The Pentagon tomorrow will conduct a test like this one, firing a mock warhead from an island in the pacific. And attempting to block it with a rocket fired from a base in California. The bottom line is, it would be a catastrophic war if this turns into a combat if we're not able to resolve this situation through diplomatic means. Now, today, Japan's prime minister condemned this new missile test saying he's working with the usa and will quote, take specific action to deter North Korea. No details yet about how they could happen. Tom. Bob from beijing, thank you.
