TASHKENT, Uzbekistan: Uzbekistan has fully reopened its only border crossing with Afghanistan, which had been closed to travelers since the Taliban took power in 2021, as it seeks to foster trade links with its neighbor. The five former Soviet republics of Central Asia — Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan — had feared the Taliban takeover would lead to the spread of radical Islamism in the region. But four years after the Taliban seized power, economic cooperation is overriding their initial security concerns.
