North Korea test-fired sea-to-surface cruise missiles in the Yellow Sea on Tuesday ahead of U.S. President Donald Trump’s visit to South Korea.

The state-run Korean Central News Agency(KCNA) reported on Wednesday that the country’s Missile Administration conducted the launch under the supervision of Pak Jong-chon, vice chairman of the Central Military Commission of the North’s ruling Workers’ Party. 

KCNA added that the cruise missiles, improved for ship-based launches, were fired vertically and flew for more than seven-thousand-800 seconds along a preset route over the Yellow Sea before striking a designated target.

Pak highlighted that the nation has achieved significant progress in putting North Korea's nuclear forces on a practical basis in line with the ruling party’s strategic objectives.

North Korean leader Kim Jong-un did not observe the test.

The launch came as Trump reiterated his willingness to meet with Kim during his trip to South Korea.
