The 133rd China Import and Export Fair opened in Guangzhou today, the first full offline edition in three years. Dongyue Machinery Co., Ltd. was back on the floor, with Chairman Sun Jingwei and Foreign Trade General Manager Sun Jinghui leading the team in person.

Their booth drew a steady stream of construction equipment buyers from the Middle East, Africa, Southeast Asia and Eastern Europe. Most came with specific questions — production capacity, mold changeover time, and whether the machines could handle local raw materials like river sand or fly ash.

On display were the QT-series block machines and the AAC panel production line, the same equipment line Dongyue had been refining since acquiring German Katzbeton cutting technology a decade earlier.

Sun Jinghui spent the morning walking a Nigerian distributor through a QT6-15 line, explaining how the dual-proportional valve system keeps block density consistent. A Russian buyer who had run a smaller Dongyue machine for six years stopped by to scale up to a QT10-15.

Both Sun Jingwei and Sun Jinghui stayed through the close of the first day, talking specs rather than small talk. "Three years offline is a long time," Sun Jingwei said. "Good to be back where buyers can put their hands on the steel."

The team expects to follow up with dozens of qualified leads before the fair ends.
