The deployment of Chinese weapons by Pakistan has several effects on the security situation in the India-Pakistan border:

• Increased military capabilities: With the deployment of advanced Chinese weaponry, Pakistan's military capabilities have increased, which could pose a challenge to India's security.
• Strategic shift: The deployment of Chinese weapons could represent a strategic shift in Pakistan's military thinking, as it may rely more heavily on China for military support than the US or other western allies.
• Escalation of tension: India is likely to view the deployment of Chinese weapons as a provocation, which could lead to an escalation of tension between the two countries.
• Balance of power: The deployment of Chinese weapons could upset the balance of power in the region, with India feeling the need to upgrade its own military capabilities to remain competitive.
• Regional stability: The increased deployment of weapons could worsen regional stability, with China and India becoming increasingly involved in the affairs of Pakistan.

In sum, the deployment of Chinese weapons by Pakistan could have both immediate and long-term effects on the security in the India-Pakistan border, with potential for heightening tensions and upsetting the regional balance of power.
