Japan is strengthening its export restrictions on South Korea. On July 4, the Tokyo government began enforcing its curbs on three types of semiconductor materials. It will decide on July 24 whether or not to remove South Korea from its 'white list' of countries that receive preferential trade treatment. Doing so would widen the number of goods under restriction to over 1,100. Tokyo's measures are likely to impact not only South Korea as a global leader in semiconductors, but also disrupt the consumer electronics industry all across the world. Some security and foreign policy experts say that the U.S. should play a mediating role as a key ally of both South Korea and Japan. In this week's edition of 'Foreign Correspondents', we sit down with our panel of journalist to get some more analysis on the Seoul-Tokyo trade war and its global impact.
