North Korean leader Kim Jong Un announced that his country will launch its first-ever military spy satellite, with the launch date undisclosed. 

The "military reconnaissance satellite No. 1" has already been built, and Kim ordered officials to speed up preparations for its launch. 

Kim addressed the satellite plans during a visit to the North Korean aerospace agency Tuesday. He stressed the need for a satellite as part of ensuring that the country effectively uses its nuclear-capable missiles. 

He cited what he described as "serious security threats" posed by "the most hostile rhetoric and explicit action" from the United States and South Korea.

Kim stressed the need for several satellites to establish a stronger intelligence-gathering capacity, the official Korean Central News Agency reported. North Korea launched a test satellite in December and published black-and-white photos showing a view of South Korean cities from space. 

Critics claimed the photos were too crude for surveillance purposes, with only large targets like warships or military installations helping to identify the area. 

Kim’s sister and senior North Korean official Kim Yo Jong said the test satellite carried a commercial camera because there was no reason to use an expensive, high-resolution camera for a single-shot test.

Kim Jong Un said one of the objectives for its spy satellite is acquiring an ability to "use pre-emptive military force when the situation demands."

Setting up the spy satellite will prove tricky, as any launch requires long-range rockets, which the U.N. has banned as part of a wider restriction against North Korea for testing long-range ballistic missiles. South Korea’s foreign ministry said the launch of a spy satellite would therefore violate multiple U.N. Security Council resolutions. 

Tensions on the Korean peninsula have hit new highs after North Korea launched a "new type of ballistic missile" last week that briefly prompted Japan to issue evacuation warnings to for Hokkaido.

China blamed the U.S. and South Korea for the flaring tensions in the region, arguing that the missile test happened as a response to joint drills between the two allies and Japan at the start of April. 

The naval anti-submarine drills marked the first joint exercise in six months, and North Korea promised to retaliate to the drills.

"The current round of tension on the peninsula has its causes. The negative impact of the U.S. military drills and deployment of strategic weapons around the peninsula is obvious to all," Chinese Ministry of Foreign Affairs spokesman Wang Wenbin said, according to Agence France Presse.
