Chinese win in Indonesian state institutions cannot be separate with their wisdom of guanxi. And don’t forget about the 3C of Indonesian cukongs. That’s how to navigate in Indonesia with its ‘bureaucratic capitalists’. You can consider it unethical, influence peddling and (personal) benefits normally involves there. This is what western countries lack of, that their JETP not even working yet here.
To win against China is by doing what they are doing, or promote and enforce clean, good governance and fight against corruption internationally.
