Lee Ji-won starts us off.
U.S. Secretary of Defense James Mattis said North Korea's ballistic missile capabilities still exist today, but that the U.S. hopes the issue can be solved through diplomacy.

At a press conference in Alaska on Tuesday, before heading to meet his counterparts in South Korea, China and Japan, Mattis told reporters that the U.S. takes Pyongyang's capabilities "very seriously".
But he added that for now,... there is full support for the diplomats who are trying to solve the issue, namely U.S. Secretary of State Mike Pompeo and National Security Advisor John Bolton,... and that the U.S. will see progress in the days and weeks ahead.

When asked if he is confident that the U.S. missile defense systems would work if needed, Mattis assured that he is absolutely confident.
And answering a question on whether there will still be a need to continue to expand the missile defense base Fort Greely in Alaska if* the current talks with North Korea bear fruit, Mattis said that even if one threat goes away, the U.S. must stay alert to other potential threats

Mattis arrived in China on Tuesday, becoming the first Defense Secretary to visit Beijing since 2014.
During his three-day stay, he will focus on improving security dialogue with Beijing. Mattis will then travel to Seoul on Thursday for talks with South Korean Defense Minister Song Young-moo, before heading to Japan.

Meanwhile,... Security Adviser John Bolton is expected in Moscow on Wednesday for talks with his Russian counterpart and possibly with Russian President Vladimir Putin.
The Kremlin said on Tuesday the two diplomats will talk about international security and stability, disarmament, regional problems and bilateral ties.
This is seen as an effort to pave the way for a possible summit between U.S. President Donald Trump and Russia's President Putin.
Bolton is due to give a news conference Wednesday afternoon on the outcome of his visit, and possibly on the details of the possible U.S.-Russia summit.
