Secretary of State Rex Tillerson on Friday put pressure on the United Nations Security Council to impose new sanctions on North Korea to end its nuclear weapons program.

A “major, major conflict” with North Korea is a possibility for the U.S., but the White House is trying to come up with diplomatic solutions, President Trump told Reuters Thursday.

Here are a few ways that could happen:

Stop Chinese missile carriers

The U.S. could start publicly calling out companies involved in North Korea’s weapons programs, such as two Chinese trucking companies that provided or helped build large vehicles that North Korea uses to transport, erect and launch its missiles, said Richard Fisher, a China and Korea analyst at the International Assessment and Strategy Center.

“In order for those trucks to carry the missile,…
