Amul's Twitter handle could be accessed when checked on Saturday afternoon and the post containing the cartoon was also visible.

"We do not know why the account was blocked as we have not received any official statement from Twitter....Amul has not run any campaign against anybody," Sodhi said.

"Amul girl campaign is on since last 55 years, and our mascot generally talks about topical subjects, reflecting the mood of the nation in a funny way," Sodhi said.

"When our advertising agency shared this ad on the night of June 4, they learnt through a forward that our Twitter account was blocked. When we requested Twitter for re-activation, the account was restored," he said.

"When we learnt about this, we asked for clarification. We do not know why this disruption occurred. We have not yet received any official message from Twitter on this," he said.

Meanwhile, #Amul began to trend on Twitter with thousands of users coming out in the company's support and accusing the microblogging platform of a bias against India.

"Fantastic by @Amul_Coop. The dragon and their slaves got scared that they restricted the account. Imagine when our Army will be knocking Chinese doors," said Twitter user Raj.

"Shocking @Twitter briefly restricted Amul account because of the post calling to boycott Chinese products. We Indians standwith our company's across India," tweeted Parth Shah.
