Japan-South Korea trade row puts hi-tech material exports at risk

South Korea threatens retaliatory moves as Japan restricts exports of hi-tech components to its companies.

It’s now feared that a dispute which began over compensating Korean labourers forced to work in imperial Japan could evolve into a trade fight.
