China's richest man is under fire over conspiracy theories that say he's secretly promoting Japan

• China's richest man is being targeted by nationalists who say he's not patriotic enough.
• Zhong Shanshan has been accused of planting images of Japan in his bottled water label designs.
• The online backlash began with the death of his competitor, Zong Qinghou.

Zhong Shanshan, the richest man in China, has been beset this month by accusations from an online nationalist crowd that he isn't loyal enough to his country.

The online anger toward Zhong, who owns the bottled water giant Nongfu Spring, evolved from questioning his patriotism to calls for a boycott of his firm built on claims that he's covertly promoting Japan.
