The most direct routes connecting the EU with China are the planned Eurasian Land Bridge across Russia and the Northern Sea Route through the Arctic Ocean, but both are comparatively underdeveloped at the moment for various reasons. In addition, while there are plans to construct a high-speed railway across Central Asia in connecting China with Iran, and thenceforth to Turkey and the EU, this idea has yet to get past the drawing board and could in any case be endangered by the regular risk of Kurdish terrorist activity in these two Great Powers’ shared Mideast borderlands. Another key point is that the US-provoked New Cold War has created artificial geopolitical obstacles to Eurasian integration as Washington seeks to “isolate” Moscow and Tehran, so there’s a chance that China’s planned corridors across its multipolar partners’ territories might not materialize as quickly as expected.
All of these factors surprisingly make the BTK railway the most presently efficient route for the EU, Turkey, and North Africa to access Central Asia, and eventually even China as well once the proper connectivity infrastructure is built in the region to facilitate this. Looking forward, while it’s doubtful that this route will ever become the primary corridor for EU-Chinese trade, it’ll probably be much more successful in strengthening Turkey’s influence in the former Soviet Republics of Central Asia, something that many Turkish strategists had spoken about and hoped for since 1991 but barely made any progress on. This could contribute to diversifying the regional governments’ foreign partnerships and, in the true sense of the word, making them more multipolar.
By establishing a more robust presence in Central Asia, which is historically in Russia’s sphere of influence, Turkey would also be expanding the complex strategic interdependency that’s developed between Moscow and Ankara since their fast-moving rapprochement kicked off last summer.
This would in turn tighten their bilateral partnership and diminish the chances that the US would ever again be successful in turning them against one another due to the heightened collateral damage that this would entail to both of their interests as a result of the long-term geopolitical changes introduced by the BTK railway.
