South Korea to stage first military parade in a decade

South Korea on Tuesday will stage its first military parade in a decade, showcasing its advanced arsenal in the face of plummeting ties with nuclear-armed North Korea.

Pyongyang regularly puts on huge military parades but such events in Seoul are traditionally only arranged every five years to mark South Korea's Armed Forces Day.

The last parade was in 2013. Five years later, then-president Moon Jae-in chose to hold a celebratory ceremony instead of a military event, in line with his conciliatory approach to North Korea.

Tuesday's parade in Seoul will begin around 4 pm (0700 GMT) and will involve around 6,700 troops and 340 pieces of military equipment, including F-35 stealth fighters, the South Korean defence ministry said.

The KF-21, South Korea's first domestically produced fighter jet, as well as next-generation helicopters and drones will also be on display, it added.

Further, around 200 South Korean and US personnel will demonstrate "tactical drops in the same way as an actual aerial infiltration", the ministry said.

President Yoon Suk Yeol, who was elected last year, has pulled South Korea closer to the United States and the longstanding allies have ramped up defence cooperation -- including large-scale drills -- to counter growing threats from North Korea.

Around 300 US military personnel will take part in the parade on Tuesday.

During a separate ceremony to mark the 75th Armed Forces Day at an air base south of Seoul on Tuesday, Yoon hailed the expansion of US-South Korea defence ties.

"If North Korea uses nuclear weapons, its regime will be brought to an end by an overwhelming response from the ROK-US alliance," he said, repeating a warning the partners have issued in the past.

- 'Visually provocative gesture' -

Despite international sanctions, North Korea has conducted a series of weapons tests this year, including the launch of intercontinental ballistic missiles (ICBMs).

Pyongyang has held three military parades this year alone, showing off a wide range of equipment including its largest Hwasong-17 ICBMs.

The parade in Seoul "is a not-so-subtle and visually provocative gesture on the part of the South Korean government of telling (North Korean leader) Kim Jong Un that Seoul will not be backing down or looking for ways to reconcile", LMI Consulting's Soo Kim, a former CIA analyst, told AFP.

South Korea is a major weapons exporter but a longstanding domestic policy prohibits it from selling arms to countries in active conflict -- such as Ukraine.

South Korea has thus resisted calls to supply weapons directly to Kyiv, despite condemning the Russian invasion.

However, any deal that sees North Korea sell arms to Russia for use in the conflict could force South Korea to review its position on Ukraine, experts say.

Last year, South Korea secured defence export deals worth $17.3 billion, including a $12.7 billion agreement with Poland -- a NATO member and key Ukraine ally -- for K9 Howitzers, K2 battle tanks and more.
