During the past eight months of the global COVID pandemic, the Chinese People’s Liberation Army (PLA) has been active in promoting China’s claims in the South China Sea.

Starting at global free trade, we show that a country gains from the introduction of (1) a small import tariff; (2) a small export subsidy, if trade costs are low and the dispersion of productivities is high; and (3) an appropriately combined small increase in its import and export tariffs.
