Do trends move from the WEST to the EAST?

It is seen that new products and concepts are innovated and launched in the West and after a succesful proven business model are the introduced in the East. We have seen this happening in almost all products from technology oriented ones like mobiles, computers and cars to consumer products like soap, foods and beverages to service based businesses like retail, hotels and franchising. Clearly, after products are successful they are simply introduced with little or no changes. The questions that occur to me are, whether this phenomenon of "WEST to EAST" is true and whether products can be successfully with little or no adaptation of the original version?
A corollary to the former question is of Eastern concepts like Ayurvedic products and a Sushi bar which are highly accepable and popular in the West and the latter stems from the success of products like Washing Machines which in a country where labour is easily and cheaply available has still been successful.
