The South Korean government's rapid response team, now on the ground in Nepal's flood and landslide zone, has begun helicopter searches. Foreign ministry officials said 10 stranded Koreans had been rescued and that searches continue for nine others out of contact.

Most of those rescued had been on trekking routes and were unable to descend after roads washed out. With communications down across a wide area, officials expect many of the missing are safe but simply unreachable.

Why the search is slow

The disaster took the form of debris flows down valleys that severed roads and bridges at once. Many stretches cannot be reached overland, leaving helicopters as the only option — and mountain weather narrows the windows in which they can fly.

Much of the local telecommunications network remains down. Individual travelers without satellite phones have no way to signal that they are alive.

How consular protection works

The episode also illustrates how consular protection functions in practice: dispatch of a response team, confirmation of whereabouts by the local mission, and negotiations to charter helicopters, in sequence.

Chinese-heritage residents of Korea holding Taiwanese or Chinese passports would go through different channels in a similar situation. Checking the contact details for one's issuing country's missions, and local emergency numbers, before traveling is practical preparation.

What comes next

Authorities plan to widen the search area as weather permits. Nepal's decision to accept foreign technical assistance opens room for multinational rescue resources to join.
