On Tuesday, a batch of imported aircraft engines for maintenance by the company waited only 20 minutes from arrival to clearance.

Leveraging the advantages of cross-border transportation provided by the bridge, the Zhuhai-based company's export of maintenance services to ASEAN countries has grown steadily in recent years, according to Liang.

"As an authorized economic operator, or AOE enterprise, we have received a lot of policy support from customs, and our market competitiveness among Southeast Asian airlines has significantly improved," said Liang.

In the first half of this year, the company's business volume with ASEAN countries increased by nearly 90 percent compared to the same period last year.
