Seoul , South Korea ( CNN ) -- South Korea 's spy chief said Wednesday that there is a high chance that North Korea will attack again following a strike last month that has led to renewed tensions on the peninsula , the Yonhap news agency reported . South Korean lawmaker Rhee Beum-Kwan quoted National Intelligence Service chief Won Sei-hoon as making the prediction , Yonhap reported . `` North Korea pushed for reckless actions as internal complaints grew over its hereditary power succession and economic situations worsened , '' the lawmaker quoted Won as saying . Meanwhile , South Korea and the United States wrapped up joint military exercises on the Yellow Sea , while South Korea carried on with plans for artillery firing drills next week amid simmering tensions with Pyongyang . The live fire drills are a routine monthly exercise aimed at securing the safety of ships in the area , the South 's Joint Chiefs of Staff told CNN . They are scheduled to begin Monday . Officials said the planned firing drills are expected to take place in waters around the Korean peninsula , including those close to the Yellow Sea border , Yonhap reported . But the Yellow Sea locations are not close to Yeonpyeong Island , where four South Koreans were killed by North Korean shelling on November 23 , Yonhap reported officials as saying . North Korea has said the South provoked the attack , which also left 18 people injured , because shells from a South Korean military drill landed in the North 's waters . Meanwhile , South Korea and the United States are reportedly in talks about more joint naval exercises for this year or next year . `` We have been in consultations with the U.S. to carry out several rounds of joint military drills to deal with a limited provocation by the enemy , '' said Col. Kim Young-cheol of the South 's Joint Chiefs of Staff , Yonhap reported . `` The timing and participating military assets have not been decided yet . '' North Korea warned Tuesday that the military drills by the United States and South Korea could lead to `` all-out war any time . '' The firmly worded message was published by North Korea 's state-run KCNA news service . `` If the U.S. and the South Korean war-like forces fire even a shell into the inviolable land and territorial waters of the DPRK , they will have to pay dearly for this , '' the news service report said . The DPRK is the acronym for North Korea 's formal name : the Democratic People 's Republic of Korea . The U.S. State Department announced Wednesday that Secretary of State Hillary Clinton will meet with ministers from South Korea and Japan next Monday to discuss the Korean crisis , among other issues . That encounter comes amid calls from China for an emergency meeting of the six major powers involved in talks about the Korean peninsula . The six countries are China , Russia , North Korea , South Korea , Japan , and the United States . South Korea has said it does n't think the time is right for a resumption of the six-party talks , but promised it would `` bear in mind '' the Chinese proposal . In Washington , a State Department official said the United States is consulting with its allies but that resuming the six-party talks `` can not substitute for action by North Korea to comply with its obligations . '' The Japanese government said one of its envoys is in Beijing , China , for discussions on the situation . As North Korea 's largest trading partner and strongest ally , China has been urged by the international community to confront the crisis . White House Press Secretary Robert Gibbs said Tuesday that China has `` a duty and an obligation to press upon the North Koreans that their belligerent behavior has to come to an end . '' A top Chinese envoy met with South Korea 's president over the weekend , and a top North Korean official arrived in Beijing , China , on Tuesday , the first visit to China by a North Korean official since the shelling of Yeonpyeong Island . CNN affiliate YTN reported that Choe Tae Bok , chairman of North Korea 's Supreme People 's Assembly , is on a five-day visit to China . Amid the international attempts to avert warfare , the strident and saber-rattling rhetoric between the Koreas remained the region 's background noise . This comes after South Korean President Lee Myung-bak warned this week that North Korea would face severe consequences if it launched another military attack across its southern border . `` If the North commits any additional provocations against the South , we will make sure that it pays a dear price without fail , '' Lee said in a nationally televised address .
