Do tariffs squeeze Chinese exporters' margins even as total exports hold steady?
Core argument: China's overall exports have remained stable because a sharp drop in exports to the US has been offset by a rise in exports to all other destinations.
The charts illustrate the key stylized facts about China’s exports in the face of US tariffs. Overall exports have remained stable (left chart), but that’s because a sharp drop in exports to the US (right chart, red line) has been offset by a rise in exports to everywhere else (right chart, blue line). There’s two possible explanations for the rise in exports to non-US countries: (i) trade diversion, whereby China exports goods that otherwise would have gone to the US to new markets; and (ii) transshipment, whereby goods are shipped to the US via third countries. Both things are likely happening, but the former probably dominates to a substantial degree. The bottom line is that US tariffs are an adverse hit to the profitability of China’s exporters, who have to accept lower prices to offload goods that otherwise would have gone to the US. If instead goods are being transshipped to the US in substantial numbers, that means higher transportation costs, which also adversely hits margins of Chinese exporters.
