> China doesn't recognize the North Korean sanctions. And this is the key. In order to the hypothetical NTT situation to be affected by US sanctions, Japan would have to recognize them. It would be up to the Japanese parliament to adopt them. US cannot force NTT unilaterally to kick out someone, NTT in Japan must be in line with Japanese law. Most countries in the world do not adopt US sanctions as their own. The sanction are being enforced worldwide via contract law (i.e. the exporting company has a contract with the US vendor that it won't sell to specified parties); not by US forcing its jurisdiction on other countries. That would result in pretty nasty questioning about democracy.
