LONDON—Britain will on Wednesday push G7 allies to get tough on China over “pernicious practices” that undermine the international trading system, calling for an overhaul of outdated and ineffective World Trade Organization rules.
Trade minister Liz Truss will host her G7 counterparts and the new head of the WTO, using Britain’s platform as current president of the group of rich countries to promote post-Brexit Britain as a leading free trade advocate.
