Regarding foreign ownership of industry in the DPRK, why would this not be counted? Dialectics teaches us that we can't just slice out parts which are in reality connected. As for mineral industries, again, wikipedia has this to say:

Mining is extensively regulated in the PRC and involves numerous regulatory bodies. The state owns all mineral rights, regardless of the ownership of the land on which the minerals are located. Mining rights can be obtained upon government approval, and payment of mining and prospecting fees.

During the Mao Zedong era, mineral exploration and mining was limited to state-owned enterprises and collectively owned enterprises and private exploration of mineral resources was largely prohibited. The industry was opened to private enterprises during the reform and opening up in the 1980s and became increasingly marketized in the 1990s. In the mid-2000s, the Chinese government sought to consolidate the industry due to concerns about underutilization of resources, workplace safety, and environmental harm. During that period, state-owned enterprises purchased smaller privately owned mines. China's mining industry grew substantially and the period from the early 2000s to 2012 is often referred to as a "golden decade" in the mining industry.

No problem on sharing this, I spend a good deal of time trying to understand China's model of socialism.
