Cambodian Senate President Hun Sen issued a stark warning on Tuesday, threatening to arrest several Thai leaders allegedly involved in the "killing" of Cambodian citizens during recent border clashes. This comes in direct response to Bangkok's announcement of legal proceedings against both Hun Sen and his son, current Prime Minister Hun Manet.

Key Developments:

1. Arrest Threat: Hun Sen declared Cambodia's readiness to detain Thai officials, stating: "If Thailand believes it can arrest Cambodian leaders, we too can arrest Thai leaders who violated our borders and killed our citizens." (Source: Khmer Times)

2. Legal Countermove: The warning follows Thai Acting Prime Minister Phumtham Vechayachai's Monday press conference announcing potential legal action against the Cambodian leaders for "military aggression and sovereignty violations."

3. Border Tensions: The long-disputed Cambodia-Thailand border has seen renewed clashes since May, despite a Malaysian-brokered ceasefire with U.S. and Chinese support.

Operational Details:

• Thai Legal Process: Complaints will be filed with the Royal Thai Police and Regional Police Command, potentially leading to arrest warrants if the Cambodian leaders enter Thailand.

• Diplomatic Fallout: Hun Sen questioned whether Thailand's actions aimed to "build trust or reignite conflict," citing alleged breaches of international customary law.

Historical Context:
The neighbors have faced recurring border disputes, particularly around temple territories, with tensions peaking during the 2008 Preah Vihear conflict. Recent months saw a fragile ceasefire collapse into mutual sovereignty accusations.
