KABUL, Afghanistan — By plane, motorbike, camper van and even on bicycles, tourists are beginning to discover Afghanistan, with solo travelers and tour groups gradually venturing into a country that until recently was wracked by war.

Afghanistan has remained largely isolated since the Taliban seized power nearly four years ago, despite subtle signs of increased cooperation with countries like China and India.

After Russia became the first country to officially recognise the Taliban government, China has welcomed the move, fuelling speculation it may be next. As regional powers deepen ties with Kabul, questions mount about the global legitimacy of Afghanistan’s isolated rulers.
