Fear of job losses was not the only concern arising from "Made in China". "Chinese products are often blamed for quality and safety problems," said Zhang Hanlin, a researcher with the University of International Business and Economics.
"The ad campaign is an effective and sophisticated attempt to reposition China as trusted manufacturer to the world drawing on international expertise," said Martin Mulligan, an observer from London.
However, different opinions have been voiced, saying the ad might be counter-productive and reinforce China's image as "the world's factory."
"We do need this kind of campaign, but what matters more is to improve the quality of our products and create China's own world-famous brands," a netizen said on China's popular online forum www.tianya.cn.
Another netizen remarked "We would like to see more 'Designed in China' rather than 'Made in China'."
Zhang Yansheng said it was a hard fact that China was now the "world's factory" as its manufacturing output was 15 percent of the world's total, compared with its 6 percent share of the world's total GDP.
He said China's future ad campaigns should focus on the topic of "upgraded 'Made in China'", telling the world that the country was on the way to become the world's innovator and designer.
