Beijing: In a veiled attack on his US counterpart Donald Trump after he raised tariffs on Chinese products, President Xi Jinping on Wednesday said it is "foolish" to believe in "superiority of civilisations" as countries cannot go into isolation and close their doors from the rest of the world.

Xi made the comments at the opening session of the Conference on Dialogue of Asian Civilizations being held here, his first comments after trade war between the US and China escalated after Trump last Friday increased the import duty on Chinese products.
