Lazaro Cardenas has a deepwater seaport, and police say the Knights Templar ship illegally mined iron ore from the city to China.
Tonnes of precursor chemicals used to manufacture illegal synthetic drugs have also been seized in the port over the past years.
The Knights Templar are one of the main suppliers of methamphetamines to the United States.
Their leader is believed to he hiding in or around Lazaro Cardenas.

Two weeks ago, the mayor of Apatzingan, another Knights Templar stronghold, was arrested on suspicion of extorting money on behalf of the cartel.
Farmers in western Michoacan state have long complained about the power of the Knights Templar and the corrupt nature of local officials.

On Monday, Mexican security forces started registering the weapons of the vigilante groups as part of a deal with the government to incorporate them into the official security forces.
