North Korea conducted a missile test over the weekend in another attempt to show defiance to the world’s sanctions.

A short-range guided missile was fired into the water off the eastern coast Sunday and three short-range missiles were fired in a test on Saturday. South Korea called the acts “provocations” but noted that no North Korea troops were moving toward the border.

“North Korea is firing guided-missiles, not ballistic missiles that could be used to carry nuclear warheads to target,” Yang Moo Jin, a professor at the University of North Korean Studies in Seoul, told Bloomberg. “The North is likely testing these missiles as an armed protest against the recent military drills jointly conducted by the U.S. and South Korea.”

A spokeswoman for the White House National Security Council told reporters in an e-mail Saturday that North Korea will only further isolate itself if it continues to take actions like the missile launches this weekend.

Analysts said that these tests will likely have no impact on the world economy as North Korea has taken actions similar to this in the past with no impact. However, if a medium or long range missile were to be launched analysts believe it could carry financial impact.
