Environment and energy ministers from the Group of 20 economies gathered in this resort town on Saturday to find innovative ways to combat emissions-driven climate change and eliminate plastic waste. But Thursday¡¯s attacks on two tankers near the Strait of Hormuz, including one operated by a Japanese company, also raised fears among the delegates about energy security.

¡°It is vital for the international community to respond collaboratively to such incidents from the perspective of ensuring global energy security,¡± he added.
