At first you need to know how many persons from Chinese counterparties will participate in your negotiation. You'd better have the same amount of team members. The team should include:
Operations Manager with the authority to cut a deal, sign a contract or write a letter of understanding.
Financial Analyst, who sends a trained business case analyst with strong business counsel skills, not an accountant who is capable of quick, high level assessments, but can follow through with detail later.
Engineer, with experience in the operations you are seeking to establish who also ideally has some business management trainings and can understand business case assessments.
Lawyer, as an adviser as contract terms can be confusing at best to the rest of the team.
Procurement Specialist, trained in international part and product sourcing if this is an essential component of the endeavor.
Marketing Specialist, trained in international marketing and with some business research background.
Professional Negotiator, who is essential if the team has little or no experience, and optional if you have a strong experienced team.
Local Interpreter, who can help you communicate well and give you guide of Chinese business culture.
Other skill sets as needed for the specific project.
