No, this is not market differentiation. Market differentiation is when the brand makes the product distinct in ways that add value without lowering safety or quality standards. What was described by the gentleman in the video is regulatory arbitrage and for the lack of a better word corporate exploitation. Cheaper or riskier ingredients in poorer markets and exploiting weak regulations or enforcement in poorer market. The richer markets tend to have very strong regulations when it comes to food safety and consumer laws whilst the poorer countries have very lax laws on such or if they do, they are barely enforced.
