India and Libya Thursday banned imports of Chinese milk products, while Gabon said it was sending back tens of thousands of boxes of contaminated milk powder.
Togo and Benin also halted imports along with Suriname, where Chinese-made sweets were stripped from supermarket shelves.
More than a dozen countries had already ordered such bans or taken other steps to curb consumption. So far, the only five cases outside mainland China of children falling ill through tainted milk have been reported in Hong Kong.
In Beijing, the Chinese government scrambled to contain the negative fall-out, signalling that it was serious about tackling the problem.
It has set up working groups in nearly every province, and embarked on a sweeping drive to set up a series of new food testing centres and replace outdated equipment, officials said.
"Our quality inspection authorities are required to establish nearly 400 product testing centres within the next two years, and 80 of these will be food testing centres," said Hou Linglin, a senior official at China's product quality watchdog.
Hou told a food safety conference in Beijing that new testing equipment was sorely needed.
"China is a large food-producing country, and the number of food items needed to be tested is growing very fast," he said.
"Although the central and local governments have increased their investment every year, currently more than 50 percent of the equipment has been used for over seven years, and is too old to be upgraded."
Meanwhile, the agriculture ministry said 29 provincial areas nationwide had set up special working groups to regulate the dairy product market, according to Xinhua news agency.
Local governments also promised subsidies for dairy farmers to reduce the cost of feeding cows, Xinhua said.
However, for all of Beijing's efforts, considerable damage has been done to the "Made in China" brand, with the milk scandal following in the wake of other scares over unsafe products from Asia's main exporting nation.
"It greatly influences people's buying decisions," Jim Cramer, an official from the Oregon state Department of Agriculture in the United States, told AFP at the food safety conference.
"It does shake the confidence of people within their own nation and obviously internationally, in the US," he added.
