We were contacted recently by a US company whose supply of products from Korea was abruptly discontinued. They had invested a lot of money in the business (tens of thousands of dollars) but were left without even a proper explanation of what had happened. My team did some preliminary research which yielded fruitful results immediately. We would have been able to get complete answers within days.
Unfortunately, the US company, unfamiliar with business in Korea, was not prepared to find out not only the history and current situation, but also proposals by the Korean side for resolution.
