"This is about currently not being able to meet in person for talks. All this of course slows down the negotiations," CEO Werner Baumann told the newspaper in an interview published on Thursday.
Court-appointed mediator Ken Feinberg told Reuters last month that the talks were slowed by the pandemic.
In the Handelsblatt interview, CEO Baumann reiterated remarks he made at the end of February that he was under no time pressure to strike a settlement deal and that he would not submit to a schedule or deadline.
