First, the Chinese SOE's wish to gain contracts acting like they are separate business from separate directives.
They must gain either funding from a few centralized SOE banks or from allowance of SOE centralized boards like the SASAC or their communist political controlled boards.
They then use more than one SOE for higher aimed resource needs to curtail the contract bidding to a higher ratio of SOE assured contract acquisition.
Then after that contract is assured the SOE cartels use an SOE cartel shipping line that is also funded and padded by SOE banks and communist political party laws and regulations.
Once those resources then get to the port they use an SOE port facility to dock and unload the resources.
From their the SOE's are shipped via SOE lines to manufacturing plants of SOE origins.
After that the product is then manufactured in SOE's style and then the SOE business seeks buyers or contracts to further their manufacturing needs to sell more as they have already created it in an SOE bank funded style of dumping tactics.
Once they have found a buyer they then ship the goods via an SOE shipping line.
Along those lines currently the SOE cartels are seeking to enter every country in the world through an SOE port system to further link the SOE straight line of business dealings.
Therefore, in this manner of straight line business dealings it would be easy to knock off a few dollars as the only entities that are currently regulating them are heavily dominated by Communist Political Party members with very little opposition political parties in the SOE regulations. This could easily lead to price fixing or even market share fixing as they public straight line of business activities is cloaked in legal and political laws.
Prodated this post however, It would not matter the evidence needed for cartel actions is gathered in the past and presented in the future.
