Resolve Vendor Non-Shipment Issue

I'm facing a critical issue with a Chinese vendor regarding non-shipment of items. Despite multiple attempts to contact them, I haven't received any resolution.

I need an experienced professional who can:
- Communicate effectively with Chinese vendors
- Navigate potential language barriers
- Resolve delivery issues efficiently

Ideal skills and experience:
- Background in international logistics or supply chain management
- Proficiency in Mandarin is a plus
- Strong problem-solving skills

Your expertise will help ensure we get the items shipped promptly.
