[Dr. Sivana]

Chinese banks raised the yuan-ruble exchange rate to capitalize on their neighbor's weakened currency.

That's not capitalizing, that's paying what the Russian Ruble is worth. Monetary markets do that, and unless you are buying futures or something, paying an exchange rate that reflects the actual value of the currency is not "capitalizing".

China raised the rates in response to the economic situation. As you say, EVERY market moves to make a profit. This is no different. Assigning an “ill intent” means that the writer doesn’t understand markets; even Chinese ones.
