China's economic success has created a fast-growing middle class and an explosion in domestic travel. Cashing in on the travel boom is one hotel chain that's expanding so fast, it's opening a new property every two days.

Budget hotel chain Hanting Inns was founded by billionaire businessman Ji Qi seven years ago. Today it has 1,000 properties in China, across four brands, and Ji expects Hanting to be the world's biggest hotel chain by 2020.

The company takes inspiration from Western low-cost hotel chains that cater for frequent business travelers on a budget, such as Accor, Ibis and Premier Inn.

"I first got the idea from a book introducing Accor, about how they open small hotels with less expensive but cozy, clean rooms," Ji told CNN's Richard Quest.

With 200 hotels planned for 2012, Hanting Hotels are targeting the frequent Chinese business travellers on a budget

"I realized there's a gap in the Chinese market for such hotels as well so I decided to invest experimentally in that niche."

Airlines are fighting for the Chinese skies as China will soon be the largest travel market in the world.

Ji identifies three things that Chinese customers look for in a hotel room -- all of which will chime with Western travelers: a soft bed, free internet access and a good hot shower after a long, tiring day.

He says his ultimate target is to open 10,000 hotels. His big draw is clean, no-frills rooms that start from as little as $15 a night.

CNN's Richard Quest puts three translation apps to the test in Beijing and Ayesha Durgahee talks to pianist Lang Lang.

"We only invest in crucial parts (of the hotels). In our lobby you don't see fancy decorations like marble surface or crystal lights," said Ji.

"We keep everything simple because our clients don't really pay much attention to that. But we put serious money into our rooms -- in that way we manage to keep our hotels cost-effective."

The sheer scale and speed of economic development within China over the last 20 years has forced hoteliers the world over to sit up and take notice. The number of Chinese people traveling outside China has risen to 65 million a year, overtaking Japan as the largest source of outbound travelers in Asia.

International hotel chains are adapting their business plans and services to cater for the increasing number of Chinese travelers.

Marriott launched its Li Yu program -- meaning "serve with courtesy" -- earlier this year, while Hilton Worldwide introduced its Huanying program last August -- tailor-made for the Chinese market, with a name that means "welcome" in Mandarin.

Paul Brown, brand president at Hilton, told Quest that Huanying offers services including Chinese foods on the breakfast menu, and guest rooms that come with green tea, slippers, and Chinese TV channels. "We wanted to create a program that made them feel comfortable and welcome when going outside their country for the first time," he said.

But international players are also moving into China . Accor has tried to gain a foothold in the Chinese market with its Grand Mercure brand, known locally as Mei Jue, and Marriott plans to more than double the number of its hotels in China in the next three years.

"We've got to make sure that we are succeeding with the Chinese traveler and winning their loyalty," said Marriott CEO Arne Sorensen. "The loyalty that we build here can get translated ultimately to loyalty of Chinese travelers going around the globe."

But Ji believes that foreign competitors will find it hard to compete with Hanting on its home turf. "We are faster. We are more cost-effective. We know our clients better," he said.
