SEOUL, Aug 5 (Reuters) - South Korean shares tumbled more

China, South Korea's largest export markets, added to the
selling pressure.

Japan tightened controls in July on exports to South Korea,
escalating a row over wartime forced labourers and sparking a
boycott by South Korean consumers of Japanese products and
services, from cars, beer and pens to tours.
"Japan's tighter export controls may dent South Korea's
capital investment, exports and private consumption, which may
lead to this year's growth rate being lower than 2%," said Lee
Kyung-su, chief of Mertiz Securities research centre.
South Korea on Monday announced plans to invest about 7.8
trillion won ($6.44 billion) in research and development for
local materials, parts and equipment over the next seven years
in an effort to cut reliance on Japanese imports. urn:newsml:reuters.com:*:nL4N25103Z
However, such measures are expected to take some time to
kick in, according to analysts.
The junior KOSDAQ .KQ11 extended its losses, triggering
the bourse to suspend future linked trades for five minutes. It
ended down 7.5%.
The KOSPI's pharmaceutical sub-index .KS32 was the biggest
percentage loser with a 8.8% drop on dampened sentiment across
the sector after SillaJen's 215600.KQ halted clinical tests.
