Anwar Ibrahim is expected to succeed the 94-year-old Mahathir Mohamad.
Malaysian Prime Minister Mahathir Mohamad has dialled back his criticism of India after it sparked a boycott of Malaysian palm oil, his chosen successor Anwar Ibrahim told Reuters on Thursday, urging New Delhi to note the change in tone.
India, the world's biggest buyer of edible oils, last month imposed curbs on refined palm oil imports and informally asked traders to stop buying from Malaysia, the world's biggest producer and exporter of the commodity after Indonesia.
Sources said the move was in retaliation for Mahathir Mohamad speaking out against citizenship amendment act, which critics say discriminates against Muslims.
Anwar Ibrahim, who expects to succeed the 94-year-old Mahathir Mohamad later this year under a deal worked out with his former foe, said the Malaysian leader may have gone beyond diplomatic expressions of concerns in his condemnation of the Indian government.
"Countries will not take strong objections when you express concern, but of course in this regard Tun Mahathir has been quite tough and strong," Anwar Ibrahim said in an interview, using an honorific for the premier.
"But since then in the past few weeks, he has tried his level best to contain and try to make the necessary adjustments. I'm sure the leaders in India will take cognisance of the fact that Mahathir did say it, but then he has now refrained from repeating it in the sayings or tone."
Anwar Ibrahim said he and Mahathir Mohammad had discussed the tension with New Delhi and that it was important to maintain good economic and trade relations with countries like India and China without necessarily having to agree with each other's policies.
India's January imports of Malaysian palm oil may have plunged 80% from a year earlier to 40,400 tonnes, according to Refinitiv
India bought 4.4 million tonnes of Malaysian palm oil last year, according to the Malaysian Palm Oil Council.
