About us

A China-focused intelligence firm for global procurement teams.

HOW WE WORK

Why we exist

Distance hides weak entities. We read the official record and deliver a signed verdict before you pay or sign.

WHY WE EXIST

How we work

We start from the entity.

You give a legal name or USCI; we scope the file to that supplier

We read the official record.

Registration, ownership, litigation, enforcement, and related public lists — in the original language.

We interpret for a decision.

Findings are cross-checked and written for payment and contracting posture.

We sign the verdict.

One clear position — with sources and a query date — not a data dump.
