In the midst of a major diplomatic row over the death of a Sikh separatist involved with the Khalistan movement, Hardeep Singh Nijjar, Canadian Prime Minister Justin Trudeau has discussed relations with India with Jordan's King on Sunday.

"The Canadian Prime Minister spoke with King Abdullah II bin Al-Hussein of Jordan on Sunday and he provided an update on the situation between Canada and India, underscoring the importance of respecting the rule of law and the Vienna Convention on Diplomatic Relations," his office said in a statement, reports NDTV.

This comes after Trudeau discussed India with the UAE president. "On the phone today, His Highness @MohamedBinZayed and I spoke about the current situation in Israel. We expressed our deep concern and discussed the need to protect civilian life. We also spoke about India and the importance of upholding - and respecting - the rule of law," Trudeau tweeted on Sunday.

Last month, the Canadian prime minister made the claim that "Indian government agents" were behind the shooting of Nijjar.

Such "credible allegations" were shared with India a longtime ago, he also said.

"Canada has shared the credible allegations that I talked about on Monday with India. We did that many weeks ago. We are there to work constructively with India. We hope that they engage with us so that we can get to the bottom of this very serious matter," the Canadian PM told a news conference.

India has flatly denied Canada's charges, calling them "absurd." According to India, Canada has not revealed any concrete information about its allegations, despite the fact that it has "politically condoned hate crimes and criminal violence" in that country. The foreign ministry has advised its nationals in Canada and those contemplating travelling there to exercise "utmost caution".
