"If one party reverses the decision of its rival dispensation upon change of guards, the policy and political risks for global investors would definitely increase in India, scaring them away," the chamber said in a statement.
After Delhi, Rajasthan has scrapped the approval given by the previous government for foreign direct investment (FDI) in multi-brand retail sector.
Rajasthan government's decision would "dent and shake the confidence" of the global investors, Assocham said, adding that a national consensus should be built on politically-sensitive issues.
"Once a stand is taken, there should be no room for reversal. Businesses all over the world do not like it. Such a thing is anti-investment," it added.
All the political parties must debate on the issue of FDI in retail as it would benefit farmers and consumers both, Assocham said.
