That's not true, actually. Most countries have adopted the DCMA or something similar to it. Also, China and most other countries are party to the World Intellectual Property Organization Treaty, signed and ratified by over 186 countries in 1996. This is where our DCMA law in the US is derived from. Yah, that's basically what I already said. But it's not quite as simple as "whoever has more money wins." The law is still based on who has a case and who doesn't. In this case, someone who illegally used your photos doesn't have much of a case. They can try costly legal maneuvers to delay trial, etc. But in the end, if you both have enough money to go to trial, the offending party will likely lose and lose a lot of money in the end.
