'Orientalist' museum doesn't sound right if the purpose of the museum is to celebrate west-east fusion. A name such as the 'weast' museum would have been more appropriate.

Here are the 1st two definitions of the word 'orientalist' that come up on Google.

1) style, artefacts, or traits considered characteristic of the peoples and cultures of Asia. (So, east only is reflected here)

2)the representation of Asia, especially the Middle East, in a stereotyped way that is regarded as embodying a colonialist attitude. (So, west over east is clearly reflected in this case)

Neither definitions apply in my humble opinion and so the name was unapproriate.
