Chinese ambassador to India Xu Feihong has said that Beijing "firmly opposes" Washington's steep tariffs on Delhi and called for greater co-operation between India and China, BBC reported.

Xu likened the US to a "bully", saying that it had long benefitted from free trade but was now using tariffs as a "bargaining chip" to demand "exorbitant prices" from other nations.

"US has imposed tariffs of up to 50% on India and even threatened for more. China firmly opposes it. Silence only emboldens the bully," Xu said on Thursday.

Earlier this month, Trump imposed a 25% penalty on India in addition to 25% tariffs for buying oil and weapons from Russia. The new rate will come into effect on 27 August, according to BBC.
