Kunzhan Ye

Construction Supply Chain & ESG Compliance Counsel

Kunzhan Ye advises construction enterprises, developers, contractors, and material suppliers on supply chain contracts, corporate legal affairs, and ESG-aligned compliance from Xiamen's Huli District — a district whose towers, port facilities, and logistics corridors reflect the construction economy in which he has worked for his entire professional life.

Kunzhan Ye is a senior partner and founding partner of Beijing Longan (Xiamen) Law Firm, with seven years of private practice. What distinguishes him is a formation that few commercial lawyers can claim: a professional background in construction engineering, followed by a period working inside one of Xiamen's leading real estate companies before he entered the law. He has therefore seen the building industry from the inside — from the drawing board and the construction site to the procurement office and the boardroom — and he brings that practical grounding to every contract he drafts, reviews, or litigates. His practice concentrates on corporate legal affairs, construction and supply chain contracts, and the growing field of environmental, social, and governance (ESG) compliance as it applies to building and infrastructure.

Professional Background

Kunzhan Ye has practiced law since 2019, building a seven-year record of service to companies across the construction, real estate, and trading sectors. Before joining the private bar, he worked at one of Xiamen's leading real estate companies, where he observed at close range how development projects actually run: land acquisition, financing, design, tendering, construction, and delivery. That in-house experience, layered on his construction engineering background, gives him an understanding of the project lifecycle that lawyers trained only in statutes rarely acquire.

He is among the founding partners of the Beijing Longan (Xiamen) office and holds the rank of senior partner — responsibilities that include not only client work but also the development of younger lawyers and the governance of the firm itself. Over his career he has handled the full spectrum of corporate legal affairs: establishing internal rules and management systems, reviewing and negotiating contracts, advising on corporate governance, and representing companies in disputes relating to sales contracts, work contracts, debt transfer agreements, private lending, factoring arrangements, construction land use rights, and construction project contracts. The list is a mirror of the commercial life of a construction company, which is precisely the point: his practice is organized around the way his clients actually do business.

Construction Supply Chain Contracts

The construction supply chain in China is long and legally intricate. A single development project may involve a land use rights holder, a developer, a general contractor, dozens of subcontractors, material suppliers, equipment lessors, factoring financiers, and surety providers — each link bound to the next by a contract that must allocate risk across years of performance. Kunzhan Ye's practice addresses this chain end to end. He handles disputes and documentation arising from construction project contracts, including issues of cost, quality, delay, and payment; work contracts for processing, installation, and other commissioned performance; and sales contracts for building materials and equipment. He is equally experienced with the financial instruments that keep construction moving — factoring contracts that convert receivables into working capital, debt transfer agreements that restructure obligations between parties, and private lending arrangements that finance projects when bank credit is unavailable.

• Construction project contract disputes, including cost, delay, quality, and payment claims
• Work, processing, and installation contracts across the construction supply chain
• Sales contracts for building materials, equipment, and supplies
• Factoring, debt transfer, and private lending arrangements for project financing

For clients, the value of this breadth is that disputes are rarely confined to a single contract: a payment failure on a construction contract can ripple into a factoring claim, a debt transfer, and a lending dispute at once. He is accustomed to tracing those connections and to resolving them either through negotiation or in court, with the construction project itself — its documents, its site records, and its commercial logic — always at the centre of the analysis.

Corporate Legal Affairs & Contract Risk Management

A second pillar of his practice is the ongoing legal management of the enterprise itself. He assists companies in establishing internal rules and management systems — the employee handbook, procurement procedures, approval chains, and compliance protocols that turn a collection of people into an institution with predictable legal behaviour. He reviews and drafts the everyday contracts on which construction businesses run: procurement agreements, subcontracting terms, equipment leases, service contracts, and sales terms. His approach to risk management is preventive: a well-drafted contract, he argues, is cheaper than a well-argued lawsuit, and the internal rule that is never invoked is the one that has already prevented a dispute from arising.

• Internal rules, management systems, and governance frameworks for enterprises
• Contract drafting, review, and negotiation across the business
• Disputes involving companies, their shareholders, and their directors
• Compliance support for procurement, tendering, and subcontracting

ESG Compliance & Sustainable Supply Chains

As environmental, social, and governance requirements take hold in China's construction and real estate sectors, ESG compliance has become a supply chain issue as much as a corporate one. Green building standards now influence design, materials, and energy performance; environmental rules govern construction waste, dust, and noise; and developers and contractors are increasingly expected to document both the sustainability credentials of the materials they buy and the labour conditions of the subcontractors they engage. Kunzhan Ye supports clients in translating these requirements into contractual and operational terms: sustainability clauses in procurement contracts, environmental compliance obligations in subcontracts, records and documentation systems that evidence compliance, and practical guidance on how green building and energy-efficiency rules affect project delivery and cost.

His construction engineering background is a genuine advantage in this work, because ESG compliance in the building sector cannot be administered from a purely legal abstraction — it must be understood in terms of materials, methods, and site operations. Whether the client is a developer responding to green building requirements, a general contractor managing subcontractor conduct, or a supplier asked to document its environmental and labour practices, he can bridge the technical and the legal, turning regulatory expectations into contracts that are enforceable and operations that are verifiable.

Approach to Practice

Kunzhan Ye's Approach to Practice reflects his origins in engineering and operations: he begins with the facts of the project, not with the law of the matter. Only after the commercial reality is fully understood does he apply legal rules to it, and he documents his advice so that every decision point is visible to the client and can be revisited as circumstances change.

• Transaction-first analysis: the commercial reality is understood before legal rules are applied
• Documentation discipline: every commitment, approval, and decision recorded and traceable
• Preventive drafting: contracts and rules designed to avoid disputes, not merely to win them
• Integrated advice: contract, governance, financing, and compliance treated as one system

"When a client entrusts a matter to me, I owe it my complete loyalty and diligence — the matter is carried as if it were my own."

This is the principle that has guided him from his earliest days in the profession: entrusted with a matter, faithful to it. His practice is built on the contract that matters most — the trust between lawyer and client.

Local Practice in Xiamen

Kunzhan Ye practices from Huli District, Xiamen — the city's gateway district, home to its port, its logistics zones, and a large share of its real estate development. Xiamen is one of China's original Special Economic Zones and a major hub for the construction, shipping, and trading industries of Fujian province and the Taiwan Strait region. The local economy gives his practice its texture: developers building along the coastline, general contractors working across the province, material traders moving goods through the port, and financiers structuring factoring and lending arrangements for projects large and small.

For companies in Huli and across Xiamen, his office offers the combination that matters most in this market: deep familiarity with the construction industry's practices, a senior partner's judgment, and the institutional resources of a long-established national law firm. Clients working in construction and real estate value a lawyer who speaks the language of the site as fluently as the language of the statute — and in Xiamen, a city built on construction and trade, that fluency is precisely what his clients rely on.
