What has offset the decline in Chinese exports since 2015? Intra-European trade

Since the mid-2010's, China's market share in global exports has stagnated, whereas it increased considerably after the turn of the century. What has offset this decline in Chinese exports? We can think of the following explanations: China has been replaced by emerging countries where labour costs are lower than in China (in Asia, Africa, etc.); China has not been replaced by other emerging countries, but there has been a substitution of regional production in OECD countries for products imported from China, i.e. a global move of reshoring and regionalisation of value chains (in Europe, North America, etc.). Exports are then concentrated within regions. Observed facts show that the end of the rise in China's market share in global trade has been offset by an end of the decline and a recovery in the market share of trade between European Union countries. It is European regional trade that has replaced Chinese exports .
