Shortly before the Spring Chinese Export Commodities Fair opened in Guangzhou in April 1983, an event took place that focused Kamm’s attention on human rights. Two young men from Hong Kong, He Enjie and Liu Zerong, hung a banner from their room in the Guangzhou Hotel denouncing China’s ruling Communist Party. They were convicted, sentenced to death, and had their appeals rejected. Their executions were carried out on September 6, 1983. Hong Kong prisoners serving sentences for counterrevolution in Mainland prisons became a top priority for Kamm after he turned to human rights work in 1990.
