Beijing and Manila traded blame over collisions between coast guard vessels in the disputed South China Sea on Monday, with China accusing the Philippines of ¡°intentionally ramming¡± one of its ships and later violating a provisional agreement on a hotly contested area of the waterway.

In a statement, the China Coast Guard said two Philippine Coast Guard ships had ¡°ignored repeated warnings¡± and sailed in an ¡°unprofessional and dangerous¡± manner near Sabina Shoal, with showing a collision occurring in the early hours of Monday.

¡°The responsibility for the collision lies entirely with the Philippine side,¡± China Coast Guard spokesperson Gan Yu said. ¡°We squarely advise the Philippine side to immediately cease its infringement and provocations, or else it will bear all the consequences.¡±
