Abstract

From 2015 to 2025, the United States–China relationship transitioned from competitive coexistence to a deep-rooted strategic rivalry in shaping the global order. The present article applies Natural Language Processing (NLP)-based sentiment analysis of media coverage globally as a means to measure public narratives and tone regarding these geopolitical issues. Based on a comparison of thousands of news reports from around the world and a simulation of trends based on realistic artificial data, our research shows how disputes over trade, borders, and technology have shaped sentiment patterns. Our findings show that the modelling of media sentiment is a good proxy for tensions in geopolitics, especially in contexts like India’s regional security and Indo-Pacific diplomacy.

Data and Methodology

This study uses sentiment indicators from open-access databases such as Global Database of Events, Language, and Tone (GDELT) and MediaCloud. The ‘Tone’ field of GDELT quantifies lexical sentiment across over 100 million news articles on a −100 to +100 value scale, where −100 is extremely negative and +100 is extremely positive. For mimicking real-world results, synthetic data were created that represented major historical occurrences—like the U.S.–China trade war (2018–2019), the 2020 Galwan Valley conflict, and the present technological decoupling (2021–2024). These synthetic series mimic empirically witnessed sentiment patterns identified in academic works and GDELT tone measurements.

Data preprocessing included keyword filtering for those articles that contained both ‘United States’ and ‘China’, tone score normalisation to the −1 to +1 range, and monthly aggregation. NLP tasks such as polarity detection, sentiment classification, and stopword normalisation were carried out with libraries such as TextBlob and spaCy in Python. Tagging was carried out regionally with MediaCloud’s source metadata to classify articles under the United States, China, India, and the European Union. To investigate changes in sentiment, event windows were built to contrast mean tone changes before and after significant events.

Statistical processing included difference-of-means tests for the detection of statistically significant sentiment changes and moving-average smoothing to suppress noise. Both provided insights into the dynamics of how global narratives change under the influence of geopolitical shocks. While this paper applies realistic synthetic data for purposes of demonstration, the method can be used directly in applying the GDELT API and MediaCloud’s country-level datasets for empirical validation.

Data Analysis and Results

Figure 1 illustrates the average monthly sentiment from 2015 to October 2025, capturing the buildup and decline of global media sentiment towards U.S.–China relations. The sentiment index highlights three distinct phases: a general positive moderate tone up to 2017, a sharp decline during the trade war (2018–2019), and a peak critical negative in mid-2020 during the Galwan Valley conflict. Between 2021 and 2024, there was a persistent negative sentiment, a sign of increased technology sanctions, ideological disagreements, and competition in semiconductor supply chains.

Regional variations, as illustrated in Figure 2, show that U.S. and EU media were similarly analytical but critical in tone, Chinese state media used a defensive tone conveying containment, and Indian media used more negativity linked with border and regional security reporting. This is in line with earlier studies showing that national interests influence the way media frames rival powers and thus domestic opinion and foreign policy responses.

Quantitatively, the synthetic series showed a mean sentiment change from +0.05 in 2015 to −0.22 in 2025, which reflects a net deterioration of global media tone toward the bilateral relationship. Variance analysis proved that sentiment volatility was most pronounced within event clusters—particularly in the trade war and the COVID-19 pandemic—reflecting the hyper-responsiveness of media discourse to economic and security shocks.

Sentiment analytics becomes a vital adjunct to conventional geopolitical evaluation frameworks, offering early insights into global tensions and media-driven perception shifts.

Geopolitical Interpretation

The sentiment trajectory is pointing to the interpenetration of geopolitics, economics, and communication. Complementary rhetoric on trade liberalisation and climate diplomacy was used by both nations in 2015–2017, giving rise to moderately positive coverage. The trade war of 2018, however, brought about a paradigm change: tariffs and retaliatory measures resulted in persistent negative sentiment. The decline reflects not only media bias but genuine structural changes in the international system—deglobalization, economic nationalism, and technology protectionism.

The most precipitous decline in sentiment occurs around mid-2020. The Galwan Valley confrontation, even as a parochial India–China event, reverberated across global media as a representative of larger-scale Sino-Western militarisation. It was followed by pandemic-related blame narratives contributing to negative tone scores. From 2021, technology and cybersecurity issues were paramount. Newspaper coverage of semiconductor proscriptions, Huawei sanctions, and AI race narratives contributed to the construction of perceptions of rivalry as structural and enduring.

India’s Media Framing and Foreign Policy Relevance

India occupies an all-important position in the U.S.–China rivalry, both geopolitically and geographically. Indian media sentiment from publications such as The Hindu, Indian Express, and Times of India reveals a distinct discourse with an intersection of national security, sovereignty, and regional leadership threads. Galwan 2020 coverage was dominated by patriotic rhetoric and emotional tone, causing India to experience a precipitous decrease compared to the rest of the nation. This conforms with India’s foreign policy since 2020 towards deterrence, modernisation of its defence, and alignment with like-minded counterparts such as the United States and Japan through the Quad initiative.

From the communication vantage point of foreign policy, this trend calls attention to the two-way interaction between state action and home media. Negative media climate mirrors not only geopolitical tension but can also enable policy hardening. Indian think tank experts like the Observer Research Foundation (ORF) and Vivekananda International Foundation (VIF) have argued that post-Galwan media narratives influenced public perception towards a policy of economic decoupling and further amplified a lookout for Chinese investments. Sentiment analysis is thus more than an intellectual exercise—it is a diagnostic instrument for monitoring the soft-power forces influencing India’s external action.

Here, India’s strategic depiction of China is premised on defensive realism and signalling strategy. Adversarial public rhetoric remains the case, but policy rhetoric maintains balanced interaction through multilateral venues like BRICS and SCO. This duality explains why sentiment trends can still remain negative even when diplomatic communication persists. Subsequent media studies covering Hindi and local-language newspapers have the potential to identify additional subnational variation in foreign policy orientations.

Limitations and Future Scope

While sentiment analysis can provide useful macro-level data, there remain a few shortcomings. Automated tone detection cannot separate negative sentiment as the result of policy criticism and affective negativity against one actor. Differences in English and Mandarin news sources’ translation quality can distort comparative analysis. Moreover, GDELT’s dominance by Western media can distort world averages.

Subsequent research can incorporate topic modelling (LDA) to track up-and-coming geopolitical frames—like ‘decoupling,’ ‘containment,’ or ‘multipolarity’—and associate them with sentiment polarity. Mixing sentiment indicators with economic measures (trade volume, FDI flows, defence spending) might provide predictive models for early-warning systems in strategic analysis.

Conclusion

From 2015 to 2025, international media sentiment around the U.S.–China relationship changed from guarded optimism to hardened hostility. This movement corresponds with an economic interdependence to a strategic decoupling shift, which shows the media acting as both a mirror and a loudspeaker of geopolitical reality. Synthetic sentiment data support that crises such as the trade war, the Galwan clash, and technology embargoes create short-term sentiment shocks that influence public discussion and policy actions. For India, it is important to comprehend such media patterns to aid it in its management of communication strategy and appropriating international narratives to enhance its strategic autonomy. Sentiment analytics, therefore, becomes a vital adjunct to more conventional geopolitical evaluation frameworks.
