The U.S. and South Korea militaries began a new, smaller-scale joint exercise Monday after the Trump administration canceled large-scale drills just days after U.S. President Donald Trump and North Korean leader Kim Jong Un met in Hanoi for their second summit that ended without any deal on denuclearizing the Korean Peninsula.

The Combined Forces Command said in a statement Monday that the two militaries will conduct the new exercise, named "Dong Maeng" in Korean, or "Alliance" in English, and other lower-level drills to replace the Foal Eagle field training. The Alliance drills are to run for nine days — half the duration of the computer-simulated Key Resolve tabletop exercise.

The new drill will focus on "strategic, operational, and tactical aspects of general military operations," the statement said.
