The USA is only super power in the world ...
USA : economic power , military power , soft power and political/diplomatic power
China : economic power and military power
India : limited economic power and limited military power
China is a potential superpower
1 -- China is unable to project its military power globally. While the USA maintains over 750 military bases worldwide and 11 nuclear powered Aircraft Carrier strike groups that control the global oceans, China's only official military base outside its borders is in Djibouti, Africa
2 -- The USA is surrounded by an entrenched network of alliances comprising the world's wealthiest and most militarily advanced nations such as NATO, the G7, the EU, Japan, Australia and South Korea.
3 -- also , American Dollar rules the overwhelming majority of global trade and central bank reserves , not Yuan or Rupi
India can not become a super power by 2030 , not even close
