Sustainable Products & Sustainable Tourism

This idea began taking shape in early 2017 , a grand dream, yet one that, for a time, was buried beneath the dust of forgetfulness. We often asked ourselves: What product would truly fit? A single standalone item, or a complete ecosystem of interconnected products? Even the project’s name once stood as an open question.

Then, an overarching yet invisible element, " the nature of self-sustaining growth " suddenly became the thread connecting our present thoughts to the selves we were in the past.

Land of Steel, is such a beautiful name. In itself, it carries the fierce vitality of the land it represents. Cu Chi is the official administrative name, yet in the memory of the world, it is the land that once endured the “earth peeling operations” of war .

More than 500,000 tons of bombs and hundreds of tons of chemical agents were dropped here.

And yet, half a century later, Cu Chi is experiencing a miraculous revival.

I vividly remember the days when Ho Chi Minh City was locked down during COVID-19 , an image mirrored in many cities around the Globe. But Cu Chi was a rare green zone: from the very start of the pandemic until lockdowns were lifted, this land remained an untouched safe area.

We witnessed self sufficient villages taking shape: fresh eggs, clean vegetables, pork, and beef were all supplied locally; neighbors cared for one another with heartfelt sincerity; each person enjoyed their own clean and open space. Our collective stayed creative, kept producing, and stood firm through every challenge.

We are grateful to be part of this extraordinary land. Then, a sudden spark lit in our minds: Should we create a “ Cu Chi 2.0 ” — Where COVID era villages become models of sustainable planning, intertwined with sustainable products?

For Land of Steel… has always existed, simply waiting to be awakened.
