There are many factors that can influence the balance of power in a negotiation. These factors are classified into 3 levels:

Macro level: STEEPLE framework: social, technological, economic, environment, political, legal and ethical

Micro level: Porter's five forces:

One-to-one buyer-supplier dynamics.

The question asks about the micro factors that increases supplier's bargaining power. Among 5 answers, only 2 are likely to increase buyer's power:

There are no close substitutes for rubber: the buyer has to buy rubber, not any other material.

Costs of changing suppliers are high: buyer entails a large barrier if they want to switch supplier.

Other answers cannot be correct because:

SRI sets up its own rubber plantation: Buyer secures its own supply

SRI's purchase amount makes significant proportion of supplier revenue: Suppliers are reliant on buyer. If the buyer stops buying from them, they can face serious cash flow problems

Rubber from different suppliers is virtually similar: undifferentiated product would shift the power balance towards buyer.

Collaborating is both assertive and cooperative. When collaborating, an individual attempts to work with the other person to find a solution that fully satisfies the concerns of both. It involves digging into an issue to identify the underlying concerns of the two individuals and to find an alternative that meets both sets of concerns. Collaborating between two persons might take the form of exploring a disagreement to learn from each other’s insights, resolving some conditionthat would otherwise have them competing for resources, or confronting and trying to find a creative solution to an interpersonal problem.

Foreign exchange ratesdirectly influence thecost of imported goods and services. Currency fluctuations can affect total expenditure, supplier margins, and ultimately the buyer’s profitability. Even if payment is in local currency, suppliers may adjust their pricing to mitigate foreign exchange risks.

“Foreign exchange volatility can significantly impact pricing in international procurement. Buyers must assess currency risks as part of their cost evaluation and strategic preparation.”

(L4M5 Commercial Negotiation, 2nd edition, Section 2.2 - Macroeconomic Considerations in Pricing)

International negotiations often face conflicts due to cultural differences (language, communication style, decision-making norms) and timing/location (time zones, travel, scheduling). These factors can cause misunderstandings or perceived power imbalances. Team size and make-up matter but are manageable internally, while closure processes can be aligned. Recognising cultural and logistical divergences allows buyers to prepare strategies that reduce conflict and promote smoother negotiations.

There are four types of questions that can be used in a commercial negotiation:

Hypothetical questions, where you ask about a possible situation or abstract concept, are very useful at the testing and proposal phases. Hypothetical question does not state any commitment as it is only about 'if something happens, then ...'. This type of question can be useful at giving suggestion.

The collaborative strategy (win-win, integrative) focuses on joint problem-solving, transparency, and trust. It is best when long-term relationships are critical, and both parties see value in mutual success. By contrast, competitive (win-lose) is adversarial, accommodative sacrifices one party’s interests, and avoidance seeks disengagement. Collaborative strategies are common in partnerships, innovation projects, and sustainable procurement. They require sharing information, identifying tradeables, and aligning objectives beyond price to long-term outcomes.
