While studying globalisation, The subject of Trade BlocksBlocs was brought up, with hindsight, I wondered, aren't Trade BlocksBlocs fostering regionalism (as in devotion to the interests of one's own region) as opposed to globalisation? Trade blocksblocs are anti-free-trade since they are essentially barriers to trade from nations outside of the blockbloc. Since Globalisation is "developed" through free trade as opposed to "regionalisation" of Trade, then are Trade BlocksBlocs regionalism and thus anti-Globalisation?
