China accounts for more than a quarter of global machine-to-machine (M2M) connections, according to a report by the GSMA association of mobile operators. With more than 50 million connections, the country's at the head of the pack when it comes to Internet of Things adoption. China's lead is thanks to strong government support - the country plans to invest more than $600 billion in IoT through the year 2020. The fact that China's top mobile operators are cooperating with the government to deploy M2M solutions across several fields doesn't hurt, either.
