KIEV, Ukraine — Russia and Russian state companies have increased the economic pressure on the new pro-Western government in Kiev over the past week, closing the border to most trucks, shutting a Ukrainian factory in Russia and yet again raising the price of natural gas.

The actions revive an array of Russian economic foreign policy tools used for years and made possible by Russia’s robust domestic consumer market and the country’s energy exports.

About a quarter of all Ukraine’s exports go to Russia, and factories here have benefited from a growing demand in the defense sector and rising consumer purchasing power.

Russia’s manipulation of gas prices under various pretexts has for a decade proved to be a particular headache for pro-Western Ukrainian governments.
