Ionescu still has 'immunity'

In my opinion, I felt that Ionescu still has his immunity as Romania will definitely be bias towards it's own citizen, furthermore, someone who has a position in its country. Also, I think that both countries Singapore and Romania have different views regarding this case. Singapore may find this a big deal but Romania might not.

Ms Irene Ng Phek Hoong: Also given that Romania does not seem to share the same understanding as Singapore that Ionescu does not have diplomatic immunity, is there a higher international body that we can turn to resolve this?

Minister George Yeo: Legally speaking, there is no higher authority we can appeal to. Because of some disagreement or confusion over the interpretation of Article 39.2 of the Vienna Convention, the earlier Interpol Red Notice has been suspended.

Quoted from the article

From this conversation, I felt that Singapore is kind of at the losing end because there isn't any other parties that we can depend on regarding this matter. After reading a comment regarding this article, it says that Singapore should send a diplomatic note to complain to the European Union about the behaviour of the ex-diplomat as well as the subsequent behaviour of the Romanian government. But the question I'm asking this commentor is that, Romania is under Europe, will the European Union will take into consideration of what Singapore suggested? If they didn't take into consideration, wouldn't it be back to square 1 again?
