The global potash market is controlled by about 10 mainly Canadian companies and a couple of Russian producers.

David Smith of Accenture Talent & Organization warns that in a time of skills shortage, employers shouldn't assume that workers have the resources or the knowledge to upskill on their own.

Smith explained, "Our study shows that workers are prepared to improve and expand their skills, but they're not receiving sufficient support to develop those skills. In addition to investing in training, employers will have to become more transparent about their talent requirements and more creative about leveraging the skills they already have within their organizations."

Wang Qishan said that a long-term global recession is certain to happen and China must focus on domestic problems.
