we dont have any issues with who controls who or what in afghanistan we made a deal with afghan government and its there problem to give the route required security as for taliban why will they create problems for there own people in getting rich and getting new source of income just because india is building it and its coming thru iran ?
your so so wrong brother Chahbahar is not in any way against Chinese intersts or there New Silk Road to central asia and Europe
see take a map and see the diffrence between Kashgar to nearest production facilty /manufacturing cities in China and there distance from kashghar and Gawadar and how much distance china needs to cover to send its goods to central asia and Euorope (new silk road)

now tell me what will be chinas priority to do trade waia land in Xi’an in central China before stretching west through Lanzhou (Gansu province), Urumqi (Xinjiang), and Khorgas (Xinjiang), which is near the border with Kazakhstan. The Silk Road then runs southwest from Central Asia to northern Iran before swinging west through Iraq, Syria, and Turkey. From Istanbul, the Silk Road crosses the Bosporus Strait and heads northwest through Europe, including Bulgaria, Romania, the Czech Republic, and Germany. Reaching Duisburg in Germany, it swings north to Rotterdam in the Netherlands. From Rotterdam, the path runs south to Venice, Italy
or the CEPC where it again has to cover all the pakistan land distance after passing to karakoram pass to reach gawadar where the good will again be loaded on ships to join maratime silk route (why will they not keep using the orignal Silk Road or the maratime silk route)
in short :
1. CEPC is just Plan B /Insurence policy for trade if the chinese martime trade is effected in SCS to mallacka straits to bay of bengal to suez canal and beyond think about it
2. Chahbahaar corridoar is not even compition to chinese trade corridoar /New Silk route /Maratime Silk Route
