UPDATE 1-Typhoon kills five Chinese fishermen off South Korea

(Updates death toll, damage, landfall)

SEOUL, Aug 28 (Reuters) - A typhoon with winds of up to 170

kmh (106 mph) buffeted South Korea's west coast on Tuesday,

killing five people at sea and leaving 10 missing when two

Chinese fishing vessels capsized.

Typhoon Bolaven barrelled up the coast before making

landfall in already flood-ravaged North Korea as the

impoverished country struggles to feed its 24 million people.

A second typhoon was making its way up a similar course on

Tuesday and was expected to hit the peninsula later in the week.

Coast guard rescuers pulled 18 surviving fishermen from the

Chinese vessels that capsized off the southern island of Jeju

and found five bodies, the emergency services said.

The storm knocked out power for nearly 200,000 homes in

South Korea and uprooted poles but there was sharply less

serious rain damage than had been feared.

China warned of possible flooding in coming days that could

hit corn and soy crops in parts of its three northeastern

provinces.

Schools were closed for the day in the South Korean capital,

Seoul, and in the south, but financial markets, industrial and

energy installations and government services operated as usual.

Hundreds of international and domestic flights were

cancelled.

Local news reports said power was cut briefly to the

petrochemical factory complex in Yeonsu, affecting LG Chemical

, Hanwha Chemical 009830.KS>, Kumcho Petrochemical

and Yeochun NCC Co but impact on production was limited.

The storm hit the southern part of North Korea's west coast,

near the farming regions surrounding the capital Pyongyang, the

South's national weather service said.

The destitute North, which has trouble feeding its people

even in years with good harvests, has said heavy rains in July

and August inundated farmland and triggered landslides, killing

hundreds and leaving families homeless.
