The 25-year-old player, who is preparing for the Munich tournament, thus joins the concert of voices which have risen against the decision to exclude the next London tournament, announced on Wednesday due to the invasion of Ukraine by Russia.
For the time being, Russian and Belarusian players can take part in ATP and WTA Tour tournaments on the condition that they do not compete under the name or flag of their country.
Zverev, on the other hand, believes that it is "completely normal" that the national teams of Russia and Belarus are excluded from any tennis competition.
The International Tennis Federation has already banned the two countries from participating in the Davis Cup and the Billie Jean King Cup.
"It's all against Russia and I can understand that," added the German, who was born in Hamburg to parents of Russian origin.
"I think we are all against war, what is happening in Ukraine is inhumane and should not happen."
Thursday, his Russian friend Andrey Rublev had judged the decision of the organizers of Wimbledon "totally discriminatory".
Rublev, his compatriot world N.2 Daniil Medvedev or the Belarusian world N.4 Aryna Sabalenka will therefore not be able to participate in Wimbledon this year (June 27-July 10).
On Wednesday, world No.1 Novak Djokovic said in Belgrade that the decision to exclude Russians and Belarusians from Wimbledon was "crazy".
Billie Jean King, American tennis legend with 12 Grand Slam titles, including six at Wimbledon, wrote in a statement on her social media on Thursday: "I cannot support the exclusion of individual athletes from any tournament on the sole ground of their nationality".
