The exact same rules for ordinary (e.g., non partner) redemptions apply. $100 redeposit fee unless you're gold (which you are). Taxes/fees go are refundable upon points redeposit; if you cancel within 24 hours, money goes to original form of payment. If you cancel after that window, funds go to travel bank. Entirely non-negotiable, in my experience (which is upwards of 5 int'l partner booking flights on VX).
