What do these numbers tell us?
Measuring and comparing volumes on the New Silk Road are always a complex matter, in the first place because there are different sources, reporting different data. The differences between these figures are due to the fact that everyone has a different definition of the New Silk Road.
Whereas some count the numbers on the main route only, others add up all the routes. While China is focused on trains to and from China, you can also consider other destinations. And then there is the question of what you count: TEU’s, the number of trains, cargo in tonnes, only containerised cargo etc.
If you have all these numbers at hand, you want to compare them to illustrate what they indicate but for that, you want to be sure not to compare two different sets of data. In conclusion, it is almost impossible to conclude how successful a year has been, taking into account all these figures.
From a Chinese perspective
This being said, we are choosing to present the numbers of the Chinese authorities in this article, as these are the numbers that have been released. We are first taking a closer look at the cargo measured in TEUs, as this provides a more inclusive image. The year 2021 can be deemed successful with a growth rate of 29 per cent, despite on ongoing pandemic, a stressed supply chain and significant congestion on the New Silk Road.
However, if you compare this with the growth rate of 2020, also a corona year, the results can be seen in a different light. The year of 2020 saw a growth rate of 56%, as 1.135 million TEUs of cargo was shipped between Europe and China that year. In 2019, this was 725.000 TEUs. Then again, the year of 2019 saw a growth rate of 34 per cent, not much higher than the year 2021.
The conclusion that 2020 was an exceptionally good year can also be drawn looking at the growth rate in the number of trains. While the year 2021 saw a growth rate of 22 per cent in the number of trains, in the year 2020 this was 50 per cent, and in the year 2019 per cent.

What is normal?
It is hard to explain these differences without looking at the last ten years. In fact, a doubling of the volumes is not an extreme. Although based on a different set of figures, counting only the volumes on the main route via Belarus, Kazakhstan and Russia, this website concluded in December 2018:
“The total volume of freight traffic transiting via the broad gauge network of Russia, Belarus and Kazakhstan amounted to 245 thousand TEUs in the first eleven months of 2018. This indicates a growth of 58 per cent in comparison to the similar period last year, when this value was 155 thousand TEUs, according to the United Transport and Logistics Company – Eurasian Rail Alliance (UTLC ERA).
“These figures indicate a continuing trend where volumes nearly or more than double each year. In 2015 traffic on this route amounted to 46,000 TEUs, while it grew to 104,500 TEUs in 2016. In 2017, the total volume was 175,000 TEUs. If this trend continues, volumes should hit a million TEUs in 2020.”
