Why Competition Lawyers in Vietnam Are Increasingly Important
Vietnam’s economy is expanding rapidly, with stronger foreign investment, more sophisticated M&A activity, growing digital platforms, and increasingly complex supply chains. These developments have made competition law more important for both local companies and foreign investors. Consequently, it is vital for businesses to consult with foreign investment lawyers in Vietnam before making investment t

Competition law issues may arise when a company:
- acquires another business in Vietnam;
- forms a joint venture with a competitor, supplier or distributor;
- appoints exclusive distributors or agents;
- sets resale prices, rebates or loyalty discounts;
- exchanges market information with competitors;
- uses a dominant market position;
- operates an e-commerce platform or digital marketplace;
- uses data, algorithms or AI in pricing, search ranking, targeting or recommendations;
- launches advertising, promotion or consumer campaigns;
- responds to complaints from competitors, customers or regulators.
Vietnam’s current competition law framework is mainly based on the 2018 Competition Law and Decree No. 35/2020/ND-CP. The Vietnam Competition Commission has described this framework as using a more substantive and effects-based approach to assess economic concentration and its impact on market structure and competition. The notification thresholds include assets, revenues, transaction value and combined market share.
This means that businesses should not assess competition risk only by asking whether a transaction or conduct is “common in the market.” They should consider whether the conduct may affect competition, consumers, market access, competitors, data control or regulatory policy in Vietnam.
Vietnam Merger Control Lawyers for M&A and Joint Ventures
Merger control is one of the most important areas where businesses need Vietnam merger control lawyers. Under Vietnamese law, certain economic concentration transactions may need to be notified to the competition authority before implementation.
Economic concentration in Vietnam may include:
- mergers;
- consolidations;
- acquisitions;
- joint ventures;
- transactions that result in control or influence over another enterprise.
Vietnam’s merger control regime is governed by the Competition Law 2018 and Decree No. 35/2020/ND-CP, which provides filing thresholds and appraisal criteria for preliminary and official reviews.
ASL LAW assists clients with:
- determining whether a transaction is notifiable in Vietnam;
- reviewing transaction structure and closing timeline;
- assessing relevant market and market share issues;
- checking asset, revenue and transaction value thresholds;
- preparing economic concentration notification dossiers;
- responding to questions from the authority;
- coordinating with foreign counsel in multi-jurisdictional filings;
- advising on closing risks and conditions precedent;
- supporting post-closing competition compliance.
Foreign investors should be especially careful because some offshore transactions may still require Vietnamese merger control assessment if they have or may have an impact on the Vietnamese market. A legal guide on Vietnam merger control notes that offshore transactions may be subject to notification where relevant parties or their affiliates have assets, sales revenue or purchase costs in Vietnam and the applicable thresholds are triggered.
Antitrust Lawyers in Vietnam for Commercial Agreements
Many competition law risks arise not from large transactions but from everyday commercial arrangements. Distribution contracts, agency agreements, franchise agreements, supply contracts, pricing policies and rebate programs may create antitrust concerns if they restrict competition or affect market access.
ASL LAW’s Vietnam Antitrust lawyers review commercial arrangements involving:
- exclusive distribution;
- selective distribution;
- resale price maintenance;
- territorial restrictions;
- customer allocation;
- non-compete obligations;
- most-favored-nation clauses;
- loyalty rebates;
- bundling and tying;
- refusal to supply;
- information exchange;
- platform terms and marketplace rules.
Our role is to help clients preserve commercial objectives while reducing legal risk. A clause may be commercially attractive but legally sensitive. In such cases, our lawyers help clients revise the structure, wording, implementation process or compliance safeguards.
This is particularly important for foreign companies entering Vietnam through distributors, local partners, franchisees, online marketplaces or sales agents.
Abuse of Dominance and Market Power Advice in Vietnam
Companies with strong market positions need careful legal review before implementing pricing, exclusivity, loyalty, data access, refusal-to-deal, platform ranking, bundling or customer restriction strategies.

ASL LAW advises clients on whether a business may be considered to hold significant market power, a dominant market position or a monopoly position under Vietnamese competition law. We also help assess whether proposed conduct may be viewed as abusive or exclusionary.
Our advice covers:
- market definition;
- market share assessment;
- barriers to entry;
- customer dependence;
- pricing and discount structures;
- exclusivity arrangements;
- refusal to deal;
- tying and bundling;
- data access and platform control;
- competitor complaints;
- regulatory risk assessment.
For companies operating in concentrated markets or regulated sectors, early competition law review can prevent costly disputes and enforcement exposure.
Unfair Competition Lawyers in Vietnam
Unfair competition is another important area where businesses may need competition law advice. Unfair competition issues often overlap with intellectual property, advertising, commercial law, consumer protection and digital platform regulation.
ASL LAW assists clients in matters involving:
- misleading advertising;
- false or comparative claims;
- misuse of trade secrets;
- passing off and brand confusion;
- unauthorized use of business reputation;
- deceptive promotions;
- unfair solicitation of customers or employees;
- unfair conduct on e-commerce platforms;
- competitor complaints and enforcement strategy.
ASL LAW’s strength in intellectual property, commercial law and dispute resolution with a highly skilled team of intellectual property lawyers in Vietnam and dispute resolution lawyers in Vietnam allows us to handle unfair competition matters from both preventive and enforcement perspectives.
Competition Law, Data Protection and Digital Markets
Modern competition law is increasingly connected with data, digital platforms, AI and consumer-facing technologies. Businesses that collect, process or control large volumes of user data may face competition and regulatory issues beyond traditional market share analysis.
ASL LAW advises digital businesses on competition and data-related issues involving:
- e-commerce platforms;
- online marketplaces;
- fintech platforms;
- education technology;
- logistics platforms;
- digital advertising;
- algorithmic recommendations;
- search ranking and visibility;
- AI-assisted pricing or targeting;
- personal data protection;
- cross-border data transfer;
- consumer protection and platform transparency.
This reflects the broader trend in which competition law, anti-trust regulation, unfair competition rules and data protection compliance are increasingly interconnected in Vietnam’s digital economy, as also emphasized in ASL LAW’s existing competition, anti-trust and data protection practice content.
Regulatory Investigations and Dawn Raid Response
Businesses may need immediate support from Antitrust lawyers in Vietnam when facing regulatory inquiries, investigation requests, document production requirements, interviews, inspections or dawn raids.
ASL LAW assists clients with:
- reviewing authority requests;
- preparing response strategies;
- collecting and organizing documents;
- advising management and employees;
- conducting internal reviews;
- assessing legal privilege and confidentiality issues;
- communicating with authorities;
- preparing remedial action plans;
- reducing future compliance risks.
Competition investigations require both legal accuracy and practical crisis management. Early legal support can help a company avoid inconsistent responses, unnecessary admissions, internal confusion or reputational damage.
Competition Compliance Training and Internal Policies
A strong competition compliance program helps businesses reduce risk before problems arise. ASL LAW develops internal policies and training programs for management, sales teams, procurement teams, legal departments, compliance officers and business development teams.
Our training programs may cover:
- basic competition law principles;
- do’s and don’ts when dealing with competitors;
- pricing and discount risks;
- distributor and agent management;
- trade association participation;
- merger control warning signs;
- abuse of dominance risk;
- document creation and email discipline;
- dawn raid response;
- data protection and digital platform compliance by data protection lawyers in Vietnam.
For multinational groups, we can localize global competition compliance policies to fit Vietnamese law and practice.
