Is there even one secondary source confirming this figure? The number of Western newspapers printing this as fact, without apparently a modicum of research, is kind of concerning. "China announces" is not the most reliable source.

Of course the Trumpist response is going to be the entire news media is failing and lying and doesn't do actual journalism and doesn't have multiple sources. The Council on Foreign Relations (CFR) published links to multiple data sources, as well as publishing the data for multiple nations as a percentage of GDP, which provides context such as that Japan is running a bigger trade surplus as a percentage of GDP. https://www.cfr.org/blog/chinas-stealth-trade-surplus

I'm doing my part!
