We don't really know the actual power mechanics, but Orbán is populist, he just do whatever the best for him. Usually that's the same as Putin wants, but last time he let other EU leaders send money to Ukraine, while he went out for a coffee break: https://www.lemonde.fr/en/international/article/2023/12/20/olaf-scholz-s-successful-coffee-break-strategy-with-viktor-orban_6359543_4.html So it's not as clear.

From this current NATO deny, some speculate he wants money from Sweden. Most EU funds are blocked, Russians don't have money anymore for him, local population don't like Chinese battery factories they planned, and other Chinese investments are also slowed down because too much was stolen.
