Chinese Economic Activity, Exchange Rates and Russia-China Trade: Evidence Consistent with an Asymmetric Structural Reorientation after 2022 Russia-China Economic Observatory
This paper analyzes monthly data from 2019 to 2025 to determine whether Chinese manufacturing activity, the CNY/RUB exchange rate, and oil prices structurally reoriented their relationship with Russia-China trade after 2022, finding evidence of asymmetric post-2022 structural instability in import equations while noting that the observed correlations do not establish causal effects.

In the world of economics, trade is often treated as a simple exchange of goods, but the forces that drive it are complex and shifting. When two nations trade, the amount of money changing hands depends on many things: how busy factories are in one country, how much oil is worth on the global market, and how the value of one currency compares to another. Usually, economists expect these relationships to be steady. If a factory in China becomes more active, it makes sense that it might buy more from its neighbors, or that its neighbors might sell more to it. If the price of oil goes up, a country that sells oil should see its total sales value rise. However, when a major global event disrupts the normal flow of business, these old rules might break. The question researchers ask is whether the relationship between these economic drivers and trade has fundamentally changed, or if the old rules still apply even when the numbers look different.
A researcher at the Russia-China Economic Observatory set out to answer this question for the trade relationship between Russia and China. They focused on the period after early 2022, a time when global trade patterns were upended by sanctions and shifting alliances. Their goal was not just to count how much money was traded, but to see if the underlying engine of that trade had been rewired. They gathered monthly data from January 2019 through September 2025, looking at three main things: how active Chinese factories were, the price of Brent crude oil, and the exchange rate between the Chinese yuan and the Russian ruble. They compared these factors against the value of goods Russia sent to China and the value of goods Russia bought from China. By separating exports from imports, they could see if the two sides of the trade relationship were reacting to the world in the same way.
The researcher found that the total value of trade between the two nations did indeed surge. On average, the monthly value of goods moving between Russia and China jumped by 83.7% after 2022 compared to the years before. Russian exports to China nearly doubled, and imports from China grew by almost 80%. Yet, this massive increase in volume did not mean the rules of the game had changed in a uniform way. When the researcher tested whether Chinese factory activity predicted Russian exports, the results were shaky. In some calculations, a rise in Chinese factory activity seemed to lead to higher Russian exports a few months later. But when the researcher removed the data from the peak of the pandemic, which had caused unusual spikes and drops, that connection disappeared. The evidence suggested that the link between Chinese factory activity and Russian exports was not a stable, reliable rule, but rather a pattern that depended heavily on specific, unusual moments in time.
The story was different for oil prices. The researcher found a clearer connection between the price of Brent crude oil and the value of Russian exports. When oil prices went up, the total value of what Russia sold to China tended to go up as well. This makes sense because Russia sells a lot of energy, so higher prices naturally raise the total dollar amount of sales. However, even this relationship was not perfect. When the researcher looked at a stricter set of data that excluded the most chaotic months of the pandemic, the connection became less certain. This suggests that while oil prices are a major driver of the total value of trade, they do not tell the whole story, and the relationship is sensitive to how the data is cleaned and analyzed.
The most significant change appeared on the import side, where Russia buys goods from China. The researcher discovered that the way the exchange rate between the two currencies affected imports had likely shifted after 2022. Before that year, the relationship between the currency values and the volume of imports followed one pattern. After 2022, that pattern changed. The data suggests that the mechanism driving imports became unstable or different, possibly due to new ways of settling payments or changes in how businesses financed their trade. Unlike the export side, where the rules seemed to wobble but remain somewhat recognizable, the import side showed a more persistent break in how the economy responded to currency changes.
Ultimately, the study concludes that the post-2022 era is not a simple reset where all old rules were replaced by new ones. Instead, it is an asymmetric reorientation. The value of trade has grown dramatically, but the reasons behind that growth are not the same for everything Russia sells as they are for everything it buys. The connection between Chinese factory activity and Russian exports is fragile and easily broken by unusual data points. The link between oil prices and exports is stronger but still depends on the specific time period being studied. The most profound change is on the import side, where the relationship between currency values and trade volume has clearly shifted, though the exact new rules are still hard to pin down. The researcher emphasizes that while the numbers show a clear change in the landscape, they cannot prove exactly why it happened or point to a single cause. The evidence points to a complex, uneven transformation where some economic ties have held firm while others have been fundamentally altered.
