Which statement is not true about Asia? ( )

参考解析：

是非题。A项，根据关键词supply chains 定位至第五段最后一句，Asia has the world's most sophisticated and productive supply chains, which are rapidly expanding into Central Asia and Africa, and are amplified by China's Belt and Road Initiative.亚洲拥有世界上最先进、最具生产力的供应链，这些供应链正迅速扩展到中亚和非洲，并因中国的“一带一路”倡议而得到放大。正确。B项，根据关键词economically integrated region定位至第四段，Asia has become one of the world's most economically integrated regions, second only to Europe, 亚洲已成为世界上经济一体化程度最高的地区之一，仅次于欧洲，尽管该地区缺乏一项区域自由贸易协定，正确。C项，根据关键词bottom-up design定位至第五段，Asia's economic integration stems from grassroots pragmatic opportunism—the exact opposite of Europe's top-down grand design.亚洲的经济一体化源于草根的务实机会主义，这与欧洲自上而下的宏伟计划正好相反。也就是说，亚洲经济一体化是自下而上的，正确。D项，关于亚洲联盟，文章中并未指出建立的难易。故本题正确答案选D。
