According to the Financial Times, the Chinese Ministry of Information and Industry Technology called for a crackdown "on illegal VoIP (voice over Internet protocol) telephone services" and is collecting evidence for legal cases against them.

China is a big player in most markets; however, when it comes to technology, powerful local companies hold sway. Last year Google (GOOG) fought a battle to keep its website in China. A couple of years ago, China set rules whereby all Internet content had to pass through censors before being approved.

It seems excitement about Apple's (AAPL) iPhone is truly global, as demand for iPhone 4 handsets has outstripped supply, according to China Unicom (CHU). Sales of the popular smartphone, which launched in China Saturday, came at a faster pace than sales of previous versions.

More than 1,000 people waited, some for two days, outside the new Apple Store that opened in Xidan Joy City shopping mall on Saturday to get their hands on the new toy.

While Apple's (AAPL) iPad has been a smashing hit, there is an onslaught of competitors gunning for the market. These include Windows 7 slates and also $35 Indian tablets. There's even buzz that Research In Motion (RIMM) will come out with the BlackPad.

So, to keep up its lead, Apple is working furiously to build supply as well as penetrate new markets. And yes, it looks like the company will move into China, perhaps as early as next month. To this end, China Unicom (CHU) will be the exclusive carrier for the iPad. This will also include the distribution of the highly popular iPhone 4.

"China is the world's biggest market for telecom services," notes Geoffrey Seiler, in an in-depth review of the leading Chinese telecom and wireless phone companies.

In his BullMarket.com, he looks at "China Mobile (NYSE: CHL), China Unicom (NYSE: CHU), and China Telecom (NYSE: CHA) noting,"There is still a lot of wireless growth potential in the world's most populated country. As such, we would expect all three to continue to grow for the foreseeable future."

Seiler explains, "China Mobile is the undisputed king of mobile from a subscriber base standpoint. Through the end of June, the company boasted 493 million subscribers. The company boasts 70% of the Chinese market.

"China Unicom (NYSE: CHU) could be one of the best ways to play China's astounding economic growth," says Brandon Clay in Invest with an Edge. Here's the growth advisor's review.

"With the world's largest population as its market, the mobile phone industry in China is set to soar. This makes China Unicom a compelling play. The firm has 21% market share in China.

"China Unicom's vice president recently said the company is targeting subscriber growth of 20 million to 30 million within a year. To put that into context, Verizon Wireless, the largest mobile phone carrier in the U.S., had 72.1 million subscribers at the end of last year.

"Holding both of China's largest wireless carriers -- China Mobile (NYSE: CHL) and China Unicom (NYSE: CHU) gives investors something of a hedge in the event that one company takes a large amount of business from the other," says China expert Jim Trippon.

In his The China Stock Alert, he adds, "Although this is a safety measure for investors, we don't expect massive erosion in either company's subscriber base as the telecom sector and 3G service continue to expand in China.

Those surprised by the market's strength in recent weeks should be even more impressed with the rebound in China, where both their market and economy have proven among the most resilient in the world.

Global specialist Nicholas Vardy adds, "While the US markets are rising, Asian stocks are on fire." ETF expert Paul Tracy adds, "China funds have screamed to the top of the performance charts."

In large part, this strength is due to the country's stimulus program. Tracy points out, "To combat the sagging global economy, Chinese Premier Wen Jiabao orchestrated a massive 4 trillion yuan ($586 billion) stimulus package.
