Technical Barriers and Trade Protection

After Uruguay round,technical barriers have become a major form for trade protection,replacing tariff barriers.However,technical barriers are not quite equal to trade protection,for it exists as it should be.In the view of origins of technical barriers,we can identify the two concepts----technical barrier and trade protection in three aspects technical difference,externality and sole protectionism;the first two aspects which we should take for granted and adopt a correct attitude to treat,the last aspect a variant of trade protection by which we should safeguard our interests.
