Trade in Textile and clothing (T&C) sector has played a leading role in transforming the economies of different countries. This can be witnessed from the role the sector has played from the development of today's advanced global economies such as the USA and the EU to alarmingly increasing economies such as China and Asian tigers. On the other hand, the T&C can also be remembered as among the highly protected sectors compared to other trade in goods. The reason for this high protection went to the sector’s significant importance and the leading role to transform a country’s economy to the industrialization peak. If we look back to the binging of the 20th century and the following several years, almost all today's developed countries had granted huge protection to the sector even though they were the preachers for the global free trade. Conversely however, today, Developed countries’ has been forcing developing and LDCs for free global trade in Textile and clothing sector. This developed countries double standard play against less developed countries to open their market for untimely global competition is as equal as kicking away the ladder, after they used it to reach the current level of development. Qualitative Doctrinal legal research method is employed in this article in order to critically examines the history of protectionism in the sector of textile and clothing trade and its current myth under the WTO agreements with recommendation that LDCs in general and Ethiopia in particular should strategically apply appropriate protectionism measures until their infant industries will be ready to compete in global market.
