IMO issue is not if China has the ability to capture Maduro like the US did, but lack of action, timidness, and political will when it comes to these types of operations. Simple truth is that the world respects and adheres to hard power, not diplomacy, negotiation, "win-win" politics, etc. Say what you will about Trump, US, Russia but they don't fear political backlash or perception on the world stage when it comes to geopolitical interests.
While I agree Taiwan is on a way higher league in the power spectrum than South American countries, a demonstration of lethal capabilities would easily solve China's annoyances in the SCS and intimindate those who challenge China's interests.
