Chinese agri-business group Sino Agro Food kicked off trading of its common shares Tuesday in the United States on OTCQX under the ticker SIAF, upgrading from the OTCQB Venture Market.

The OTCQX Market is the "top tier" of the US over-the-counter markets operated by OTC Markets Group, the group said in a statement.

It is reserved for established investor-focused companies meeting high financial and governance standards, and sponsored by professional third party advisors.

Sino Agro has qualified to trade on OTCQX US Premier, for which eligibility standards are higher still.
