Peter Thorslund Kjær, vice president of legal affairs for the Lego Group, said: "We will continue our efforts to ensure that parents and children are able to make informed choices when they are buying toy products, and that they are not misled by attempts by irresponsible companies to make toy products appear as something that they are not."
A decade long run of sales growth ended for Lego this year, after its expansion failed to deliver expected sales growth.
Chairman Jorgen Vig Knudstorp said he was "pressing the reset button for the entire group" in a bid to arrest the declines, which came after investment to boost production capacity "to support higher expectations of revenue which failed to materialise".
The Chinese market is key to Lego's future success. Knudstorp has spoken in the past of his desire to make Lego the country's number one toy brand and it opened its first factory in China a year ago.
The company is banking on sales in the world's second largest economy to offset slower sales in Europe and the US.
