PresterJohn is right. In our industry (Industrial electronics) there are plenty of examples of Spanish importers/distributors of Chinese power supplies, that have invested time and money in warehousing, setting-up distribution network, advertising, gathering technical data and manuals, trips to China, bought massive stocks and THEN a few months later some backstreet outfit is selling the same items, often with the same brand name and have bought them direct from the manufacturer. A distribution agreement with these people means nothing. Strangely enough this is a Taiwanese manufacturer, so you can imagine what mainland ones are like.
Chinese businessmen have been described variously as "having high business acumen but low business ethics" and having "a culture of corruption that makes African dictators look like philanthropists".
