Lex: Currency wars
Beijing was asking for it. On Friday a central bank official invited the US to refrain from "politicising" China's currency policy. On Sunday, closing the annual meeting of lawmakers, Premier Wen did little else, with a series of pointed allusions to the "Three Ts" dominating the two nations' relationship: Taiwan, Tibet and the trade surplus.
