The incredibly short treaty (I’m surprised the comments haven’t linked yet) lacks an expulsion provision.
At best, per article 13, every other party may (with 1 year notice) withdraw from the treaty & join a new treaty excluding the party they want to expel.
Article 8 prohibits parties of the treaty from entering “into any international engagement in conflict with this Treaty”.
A unanimous agreement to change the treaty to enable expulsion is another possibility.
