India on Wednesday summoned a top United States diplomat after Washington said it was "closely watching" events following the jailing of a senior opposition leader Arvind Kejriwal weeks ahead of parliamentary elections.
The US State Department had urged India to ensure a "fair, transparent, and timely legal process" for Kejriwal, chief minister of Delhi, who was arrested last week in connection with a long-running corruption probe.
"We take strong objection to the remarks," India's foreign ministry said in a statement. "In diplomacy, states are expected to be respectful of the sovereignty and internal affairs of others".
Local broadcasters showed the senior US diplomat Gloria Berbena entering India's foreign ministry. There was no immediate response from the US embassy.
India and the US enjoy close, strategic ties and Washington has increasingly come to see New Delhi as an important partner in its effort to push back against China's growing power worldwide.
Last week, Germany raised its concerns about the arrest of Kejriwal, a key leader in an opposition alliance formed to compete against Prime Minister Narendra Modi in elections beginning next month.
The foreign ministry said it had also summoned Germany's deputy ambassador on Saturday.
Kejriwal's government is accused of receiving kickbacks while handing out liquor licences to private companies.
He has denied the charges, and supporters say his arrest is meant to sideline challengers to Modi before next month's election - accusations the foreign ministry rejected.
"India's legal processes are based on an independent judiciary which is committed to objective and timely outcomes," it added.
India's main financial investigation agency, the Enforcement Directorate (ED), which arrested Kejriwal, has launched probes into at least four other state chief ministers or their family members.
Critics have accused Modi of politicising India's justice system.
Nearly a billion Indians will vote to elect a new government in six-week-long parliamentary elections starting on April 19, the largest democratic exercise in the world. (AFP)
