Hmm, the Xim appear to be of too little mercantile importance and severely lack the expansionist drive necessary to be considered fit for aiding the Republic's policy of rigid internationalism at the cost of native populations' cultural and economic integrity. We gleefully accept the Federation's offer of alliance.

Boooo!

Although, while the Xim do have a strong economy, you're right about the lack of mercantile importance. They aren't much for trading or warfare or expanding. But they're the most technologically advanced races in everything except weaponry and ships.
