A recent report has described China’s increasingly confrontational approach in the South China Sea as part of a broader pattern of coercion, arguing that repeated encounters with the Philippines and other Southeast Asian countries could be exposing deeper insecurities in Beijing’s regional strategy.

What happened at Second Thomas Shoal?

The July 20 confrontation between Chinese and Philippine personnel at the Second Thomas Shoal was described by a report in Japan Forward as another episode in a years-long pattern of tensions in the South China Sea.

The shoal has been a recurring flashpoint between Beijing and Manila, particularly over Philippine resupply missions to a grounded Philippine Navy vessel in the disputed area.

According to the report, Chinese Coast Guard personnel physically confronted Philippine Navy sailors during the latest confrontation. It also cited reports that a baton was used against a Filipino serviceman.

The incident occurred shortly before an ASEAN Foreign Ministers’ meeting, adding diplomatic pressure to an already sensitive regional gathering.

Manila and Beijing trade accusations

The confrontation quickly resulted in competing accusations from China and the Philippines.

Manila accused Beijing of aggression, while China blamed the Philippines for provoking the incident.

Philippine President Ferdinand Marcos Jr. summoned the Chinese ambassador and issued a strong reprimand following the confrontation.

Chinese Foreign Minister Wang Yi was in Manila on a goodwill visit at the time. According to the report, Wang acknowledged that bilateral relations had reached a “critical crossroads”.

The incident therefore moved beyond a confrontation between maritime personnel and became a diplomatic issue involving the leadership of both countries.

A pattern of confrontations in the South China Sea

The report argued that the July incident should not be viewed in isolation.

It pointed to what it described as a years-long pattern in which China has increasingly relied on maritime pressure and coercive tactics in its dealings with rival claimants in the South China Sea.

According to the report, Philippine resupply vessels have faced the use of water cannons and Chinese vessels have been involved in ramming incidents near disputed areas such as Scarborough Shoal.

The report also referred to allegations that lasers were used against Vietnamese fishermen.

These incidents have contributed to growing concern among Southeast Asian governments over China's increasingly assertive maritime behaviour.

Why the South China Sea matters

The South China Sea is one of the most strategically important and contested maritime regions in the world.

Several countries have overlapping territorial and maritime claims in the region, while the area is also important for international shipping, fisheries, natural resources and regional security.

The report noted that incidents involving coast guards, naval personnel or fishing vessels can quickly develop into diplomatic crises.

A confrontation involving one Southeast Asian country can also affect relationships among ASEAN members and influence the strategic calculations of the United States and its regional partners.

Has China’s approach strengthened regional opposition?

One of the report’s central arguments is that China's coercive tactics may be producing an outcome contrary to Beijing's strategic interests.

Rather than weakening resistance to China, repeated confrontations could encourage Southeast Asian countries to coordinate more closely over maritime security.

The report argued that individual incidents may appear relatively limited, but their cumulative effect could contribute to greater regional concern about China's intentions.

It also suggested that these confrontations have created diplomatic opportunities for the United States, allowing Washington to strengthen its relationships with Southeast Asian partners without necessarily having to intervene directly in every incident.

The Philippines-China relationship at a critical point

The latest confrontation came at a particularly sensitive stage in Philippines-China relations.

Manila has taken a more assertive position on its maritime claims under President Ferdinand Marcos Jr, while continuing to maintain diplomatic and economic engagement with Beijing.

China, meanwhile, continues to reject Philippine claims and maintains that its actions in disputed waters are intended to protect its territorial sovereignty.

The repeated maritime confrontations have made managing bilateral relations increasingly difficult.

Wang Yi’s reference to a “critical crossroads” therefore reflected the seriousness of the diplomatic situation, according to the report.

What does the report mean by China’s ‘insecurities’?

The report goes beyond describing individual maritime incidents and offers a broader interpretation of China’s behaviour.

It argues that a major power confident about its long-term position would have less need to repeatedly demonstrate its strength through confrontations involving coast guard vessels.

The report therefore interprets the frequency of such incidents as potentially reflecting strategic insecurity rather than simply confidence.

This is the report’s assessment rather than an established fact about Chinese decision-making. Beijing has consistently presented its actions in the South China Sea as defending its sovereignty and maritime rights.

ASEAN faces a difficult balancing act

The continuing disputes also present a challenge for ASEAN.

Southeast Asian countries have different economic and strategic relationships with China, while several are directly involved in territorial disputes in the South China Sea.

This makes a unified regional response difficult.

At the same time, repeated confrontations can increase pressure on ASEAN members to strengthen cooperation on maritime security and international law.

The July incident therefore had significance beyond the Philippines-China relationship, particularly because it occurred around an important ASEAN diplomatic meeting.

The wider US-China strategic competition

The South China Sea is also part of the broader strategic competition between China and the United States in the Indo-Pacific.

Washington has repeatedly reaffirmed its security commitments to the Philippines, while US and Philippine forces conduct military exercises and maritime cooperation.

For the United States, maintaining regional partnerships is a key component of its Indo-Pacific strategy.

For China, meanwhile, the involvement of the US in disputes involving its neighbouring countries is viewed as an external challenge to Beijing’s regional interests.

Consequently, relatively small maritime incidents can have implications for the wider balance of power in the Indo-Pacific.

Why repeated confrontations matter

The significance of the Second Thomas Shoal incident lies not only in what happened on July 20 but also in the pattern of incidents surrounding it.

Repeated confrontations can gradually erode trust, make diplomatic engagement more difficult and increase the possibility that an accident or physical confrontation could escalate.

For the Philippines, the issue is closely connected to its maritime claims and its relationship with both China and the United States.

For ASEAN, the challenge is maintaining regional stability while member states have different approaches to Beijing.

For China, repeated confrontations may reinforce its determination to defend its claims but could simultaneously encourage neighbouring countries to strengthen security cooperation with one another and with the United States.

The report’s argument that these actions reveal Chinese insecurity is an interpretation rather than a definitive assessment of Beijing’s motives. However, the broader concern over repeated maritime confrontations is significant because each incident can add pressure to an already tense regional security environment.

What happens next?

The immediate challenge for China and the Philippines will be preventing future maritime encounters from escalating while maintaining diplomatic channels.

Continued confrontations could place additional pressure on bilateral relations and complicate ASEAN diplomacy.

At the same time, Southeast Asian governments are likely to continue balancing economic ties with China against concerns over maritime security and territorial disputes.

The South China Sea will therefore remain a key test of regional diplomacy, ASEAN unity and the broader strategic competition between China and the United States.
