Nike Chief Executive Mark Parker said on Thursday the footwear and athletic apparel company was considering shifting its production within China following a major strike at a supplier's factory, Reuters reported on Thursday.

Thousands of shoe factory workers staged a strike earlier this month over conditions at Hong Kong-listed Yue Yuen Industrial Holdings Ltd - a $5.6 billion manufacturer of footwear for Nike Inc, Adidas and other international brands.

Mark Parker said Nike was in "close contact" with Yue Yuen and its workforce to determine if the labor conditions at the factory violate Nike's workplace standards, but added Nike had not yet "taken a position on that."
